Evolutionary Scale Modeling

Update April 2023: Code for the two simultaneous preprints on protein design is now released! Code for "Language models generalize beyond natural proteins" is under examples/lm-design/. Code for "A high-level programming language for generative protein design" is under examples/protein-programming-language/.

This repository contains code and pre-trained weights for Transformer protein language models from the Meta Fundamental AI Research Protein Team (FAIR), including our state-of-the-art ESM-2 and ESMFold, as well as MSA Transformer, ESM-1v for predicting variant effects and ESM-IF1 for inverse folding. Transformer protein language models were introduced in the 2019 preprint of the paper "Biological structure and function emerge from scaling unsupervised learning to 250 million protein sequences". ESM-2 outperforms all tested single-sequence protein language models across a range of structure prediction tasks. ESMFold harnesses the ESM-2 language model to generate accurate structure predictions end to end directly from the sequence of a protein.

In November 2022, we released v0 of the ESM Metagenomic Atlas, an open atlas of 617 million predicted metagenomic protein structures. The Atlas was updated in March 2023 in collaboration with EBI. The new v2023_02 adds another 150 million predicted structures to the Atlas, as well as pre-computed ESM2 embeddings. Bulk download, blog post and the resources provided on the Atlas website are documented on this README.

In December 2022, we released two simultaneous preprints on protein design.

• "Language models generalize beyond natural proteins" (PAPER, CODE) uses ESM2 to design de novo proteins. The code and data associated with the preprint can be found here.
• "A high-level programming language for generative protein design" (PAPER, CODE) uses ESMFold to design proteins according to a high-level programming language.

Main models you should use <a name="main-models"></a>

For a complete list of available models, with details and release notes, see Pre-trained Models.

Usage <a name="usage"></a>

Quick start <a name="quickstart"></a>

An easy way to get started is to load ESM or ESMFold through the HuggingFace transformers library, which has simplified the ESMFold dependencies and provides a standardized API and tools to work with state-of-the-art pretrained models.

Alternatively, ColabFold has integrated ESMFold so that you can easily run it directly in the browser on a Google Colab instance.

We also provide an API which you can access through curl or on the ESM Metagenomic Atlas web page.

curl -X POST --data "KVFGRCELAAAMKRHGLDNYRGYSLGNWVCAAKFESNFNTQATNRNTDGSTDYGILQINSRWWCNDGRTPGSRNLCNIPCSALLSSDITASVNCAKKIVSDGNGMNAWVAWRNRCKGTDVQAWIRGCRL" https://api.esmatlas.com/foldSequence/v1/pdb/

For ESM-MSA-1b, ESM-IF1, or any of the other models you can use the original implementation from our repo directly via the instructions below.

Getting started with this repo <a name="repostart"></a>

As a prerequisite, you must have PyTorch installed to use this repository.

You can use this one-liner for installation, using the latest release of esm:

pip install fair-esm  # latest release, OR:
pip install git+https://github.com/facebookresearch/esm.git  # bleeding edge, current repo main branch

To use the ESMFold model, make sure you start from an environment with python <= 3.9 and pytorch installed. Then add the [esmfold] option to your pip install, which will install the dependencies for OpenFold automatically. Openfold installation requires nvcc.

pip install "fair-esm[esmfold]"
# OpenFold and its remaining dependency
pip install 'dllogger @ git+https://github.com/NVIDIA/dllogger.git'
pip install 'openfold @ git+https://github.com/aqlaboratory/openfold.git@4b41059694619831a7db195b7e0988fc4ff3a307'

NOTE: If openfold installation fails, please double check that nvcc is available and that a cuda-compatable version of PyTorch has been installed.

Alternatively, we provide the esmfold conda environment, which can be built via conda env create -f environment.yml.

We also support PyTorch Hub, which removes the need to clone and/or install this repository yourself:

import torch
model, alphabet = torch.hub.load("facebookresearch/esm:main", "esm2_t33_650M_UR50D")

After pip install, you can load and use a pretrained model as follows:

import torch
import esm

# Load ESM-2 model
model, alphabet = esm.pretrained.esm2_t33_650M_UR50D()
batch_converter = alphabet.get_batch_converter()
model.eval()  # disables dropout for deterministic results

# Prepare data (first 2 sequences from ESMStructuralSplitDataset superfamily / 4)
data = [
    ("protein1", "MKTVRQERLKSIVRILERSKEPVSGAQLAEELSVSRQVIVQDIAYLRSLGYNIVATPRGYVLAGG"),
    ("protein2", "KALTARQQEVFDLIRDHISQTGMPPTRAEIAQRLGFRSPNAAEEHLKALARKGVIEIVSGASRGIRLLQEE"),
    ("protein2 with mask","KALTARQQEVFDLIRD<mask>ISQTGMPPTRAEIAQRLGFRSPNAAEEHLKALARKGVIEIVSGASRGIRLLQEE"),
    ("protein3",  "K A <mask> I S Q"),
]
batch_labels, batch_strs, batch_tokens = batch_converter(data)
batch_lens = (batch_tokens != alphabet.padding_idx).sum(1)

# Extract per-residue representations (on CPU)
with torch.no_grad():
    results = model(batch_tokens, repr_layers=[33], return_contacts=True)
token_representations = results["representations"][33]

# Generate per-sequence representations via averaging
# NOTE: token 0 is always a beginning-of-sequence token, so the first residue is token 1.
sequence_representations = []
for i, tokens_len in enumerate(batch_lens):
    sequence_representations.append(token_representations[i, 1 : tokens_len - 1].mean(0))

# Look at the unsupervised self-attention map contact predictions
import matplotlib.pyplot as plt
for (_, seq), tokens_len, attention_contacts in zip(data, batch_lens, results["contacts"]):
    plt.matshow(attention_contacts[: tokens_len, : tokens_len])
    plt.title(seq)
    plt.show()

ESMFold Structure Prediction <a name="esmfold"></a>

After installing with the [esmfold] option, you can use the ESMFold structure prediction model as follows:

import torch
import esm

model = esm.pretrained.esmfold_v1()
model = model.eval().cuda()

# Optionally, uncomment to set a chunk size for axial attention. This can help reduce memory.
# Lower sizes will have lower memory requirements at the cost of increased speed.
# model.set_chunk_size(128)

sequence = "MKTVRQERLKSIVRILERSKEPVSGAQLAEELSVSRQVIVQDIAYLRSLGYNIVATPRGYVLAGG"
# Multimer prediction can be done with chains separated by ':'

with torch.no_grad():
    output = model.infer_pdb(sequence)

with open("result.pdb", "w") as f:
    f.write(output)

import biotite.structure.io as bsio
struct = bsio.load_structure("result.pdb", extra_fields=["b_factor"])
print(struct.b_factor.mean())  # this will be the pLDDT
# 88.3

Besides esm.pretrained.esmfold_v1() which is the best performing model we recommend using, we also provide esm.pretrained.esmfold_v0() which was used for the experiments in Lin et al. 2022.

We also provide a command line interface (esm-fold) that efficiently predicts structures in bulk from a FASTA file using ESMFold:

usage: esm-fold [-h] -i FASTA -o PDB [--num-recycles NUM_RECYCLES]
                [--max-tokens-per-batch MAX_TOKENS_PER_BATCH]
                [--chunk-size CHUNK_SIZE] [--cpu-only] [--cpu-offload]

optional arguments:
  -h, --help            show this help message and exit
  -i FASTA, --fasta FASTA
                        Path to input FASTA file
  -o PDB, --pdb PDB     Path to output PDB directory
  --num-recycles NUM_RECYCLES
                        Number of recycles to run. Defaults to number used in
                        training (4).
  --max-tokens-per-batch MAX_TOKENS_PER_BATCH
                        Maximum number of tokens per gpu forward-pass. This
                        will group shorter sequences together for batched
                        prediction. Lowering this can help with out of memory
                        issues, if these occur on short sequences.
  --chunk-size CHUNK_SIZE
                        Chunks axial attention computation to reduce memory
                        usage from O(L^2) to O(L). Equivalent to running a for
                        loop over chunks of of each dimension. Lower values
                        will result in lower memory usage at the cost of
                        speed. Recommended values: 128, 64, 32. Default: None.
  --cpu-only            CPU only
  --cpu-offload         Enable CPU offloading

The command will make one prediction for every sequence in the fasta file. Multimers can be predicted and should be entered in the fasta file as a single sequence, with chains seprated by a ":" character.

By default, predictions will be batched together so that shorter sequences are predicted simultaneously. This can be disabled by setting --max-tokens-per-batch=0. Batching can significantly improve prediction speed on shorter sequences.

The --cpu-offload flag can be useful for making predictions on longer sequences. It will attempt to offload some parameters to the CPU RAM, rather than storing on GPU.

Finally, the ablation experiments for LMs of varying sizes Lin et al. 2022 table S1 are released as esm.pretrained.esmfold_structure_module_only_*(). We don't recommend using these models for structure prediction.

Compute embeddings in bulk from FASTA <a name="bulk_fasta"></a>

We provide a command line interface (esm-extract) that efficiently extracts embeddings in bulk for a FASTA file from the ESM:

usage: esm-extract [-h] [--toks_per_batch TOKS_PER_BATCH]
                   [--repr_layers REPR_LAYERS [REPR_LAYERS ...]] --include
                   {mean,per_tok,bos,contacts}
                   [{mean,per_tok,bos,contacts} ...]
                   [--truncation_seq_length TRUNCATION_SEQ_LENGTH]
                   model_location fasta_file output_dir

Extract per-token representations and model outputs for sequences in a FASTA
file

positional arguments:
  model_location        PyTorch model file OR name of pretrained model to
                        download (see README for models)
  fasta_file            FASTA file on which to extract representations
  output_dir            output directory for extracted representations

optional arguments:
  -h, --help            show this help message and exit
  --toks_per_batch TOKS_PER_BATCH
                        maximum batch size
  --repr_layers REPR_LAYERS [REPR_LAYERS ...]
                        layers indices from which to extract representations
                        (0 to num_layers, inclusive)
  --include {mean,per_tok,bos,contacts} [{mean,per_tok,bos,contacts} ...]
                        specify which representations to return
  --truncation_seq_length TRUNCATION_SEQ_LENGTH
                        truncate sequences longer than the given value

The following commands allow the extraction of the final-layer embedding for a FASTA file from the ESM-2 model:

esm-extract esm2_t33_650M_UR50D examples/data/some_proteins.fasta \
  examples/data/some_proteins_emb_esm2 --repr_layers 0 32 33 --include

python scripts/extract.py esm2_t33_650M_UR50D examples/data/some_proteins.fasta \
  examples/data/some_proteins_emb_esm2 --repr_layers 0 32 33 --include mean per_tok

A cuda device is optional and will be auto-detected.

Directory some_proteins_emb_esm2/ now contains one .pt file per FASTA sequence; use torch.load() to load them. scripts/extract.py has flags that determine what's included in the .pt file:

• --repr-layers (default: final only) selects which layers to include embeddings from.
• --include specifies what embeddings to save. You can use the following:
  • per_tok includes the full sequence, with an embedding per amino acid (seq_len x hidden_dim).
  • mean includes the embeddings averaged over the full sequence, per layer.
  • bos includes the embeddings from the beginning-of-sequence token. (NOTE: Don't use with the pre-trained models - we trained without bos-token supervision)

CPU offloading for inference with large models <a name="fsdp"></a>

If you want to load very large models like 15B and/or do inference on long sequences on your machine, regular GPU inference may lead to OOM errors. We show how to load the model with Fairscale's Fully Sharded Data Parallel (FSDP) and use its CPU offloading feature. This allows to do inference of large models on a single GPU. Please check out examples/esm2_infer_fairscale_fsdp_cpu_offloading.py for more details.

Zero-shot variant prediction <a name="zs_variant"></a>

See "examples/variant-prediction/" for code and pre-trained weights for the ESM-1v models described in Language models enable zero-shot prediction of the effects of mutations on protein function. (Meier et al. 2021).

Note that ESM-2 could be used for variant prediction as well, and is expected to have similar performance to ESM-1v.

Inverse folding <a name="invf"></a>

See "examples/inverse_folding/" for detailed user guide. The ESM-IF1 model is described as GVPTransformer in Learning inverse folding from millions of predicted structures. (Hsu et al. 2022).

We also provide a colab notebook for the sequence design and sequence scoring functionalities.

<img src="https://colab.research.google.com/assets/colab-badge.svg">

The ESM-IF1 inverse folding model is built for predicting protein sequences from their backbone atom coordinates. We provide scripts here 1) to sample sequence designs for a given structure and 2) to score sequences for a given structure.

Trained with 12M protein structures predicted by AlphaFold2, the ESM-IF1 model consists of invariant geometric input processing layers followed by a sequence-to-sequence transformer, and achieves 51% native sequence recovery on structurally held-out backbones with 72% recovery for buried residues. The model is also trained with span masking to tolerate missing backbone coordinates and therefore can predict sequences for partially masked structures.

Sample sequence designs for a given structure

The environment setup is described in this subsection of examples/inverse_folding.

To sample sequences for a given structure in PDB or mmCIF format, use the sample_sequences.py script. The input file can have either .pdb or .cif as suffix.

For example, to sample 3 sequence designs for the golgi casein kinase structure (PDB 5YH2; PDB Molecule of the Month from January 2022), we can run the following command from the esm root directory:

python examples/inverse_folding/sample_sequences.py examples/inverse_folding/data/5YH2.pdb \
  --chain C --temperature 1 --num-samples 3 --outpath examples/inverse_folding/output/sampled_sequences.fasta

The sampled sequences will be saved in a fasta format to the specified output file.

The temperature parameter controls the sharpness of the probability distribution for sequence sampling. Higher sampling temperatures yield more diverse sequences but likely with lower native sequence recovery. The default sampling temperature is 1. To optimize for native sequence recovery, we recommend sampling with low temperature such as 1e-6.

Scoring sequences

To score the conditional log-likelihoods for sequences conditioned on a given structure, use the score_log_likelihoods.py script.

For example, to score the sequences in examples/inverse_folding/data/5YH2_mutated_seqs.fasta according to the structure in examples/inverse_folding/data/5YH2.pdb, we can run the following command from the esm root directory:

python examples/inverse_folding/score_log_likelihoods.py examples/inverse_folding/data/5YH2.pdb \
  examples/inverse_folding/data/5YH2_mutated_seqs.fasta --chain C \
  --outpath examples/inverse_folding/output/5YH2_mutated_seqs_scores.csv

The conditional log-likelihoods are saved in a csv format in the specified output path. The output values are the average log-likelihoods averaged over all amino acids in a sequence.

For more information, see "./examples/inverse_folding/" for detailed user guide.

ESM Metagenomic Atlas <a name="atlas"></a>

Please visit the ESM Metagenomic Atlas website, and see our blog post to learn more.

Bulk download instructions available at a seperate README here.

The Atlas resources include a page to fold a sequence using ESMFold, searching a subset of the ESM Atlas by structure or sequence, as well as an API to access those resources programmatically.

Foldseek provides search against the Atlas without the length limitation here.

Notebooks <a name="notebooks"></a>

Inverse folding - predicting or scoring sequences based on backbone structures

<img src="https://colab.research.google.com/assets/colab-badge.svg">

The ESM-IF1 inverse folding model predicts protein sequences from their backbone atom coordinates, trained with 12M protein structures predicted by AlphaFold2. This notetook guide you through examples of sampling sequences, calculating conditional log-likelihoods, and extracting encoder output as structure representation.

Supervised variant prediction - training a classifier on the embeddings

<img src="https://colab.research.google.com/assets/colab-badge.svg">

To help you get started with using the embeddings, this jupyter notebook tutorial shows how to train a supervised variant predictor using embeddings from ESM-1. You can adopt a similar protocol to train a model for any downstream task, even with limited data. First you can obtain the embeddings for examples/data/P62593.fasta either by downloading the precomputed embeddings as instructed in the notebook or by running the following:

# Obtain the embeddings
python scripts/extract.py esm1v_t33_650M_UR90S_1 examples/data/P62593.fasta \
  examples/data/P62593_emb_esm1v --repr_layers 33 --include mean

Then, follow the remaining instructions in the tutorial. You can also run the tutorial in a colab notebook.

Note, alternatively use the newer instructions for zero-shot variant prediction, which predicts mutational effects without any supervised training.

Unsupervised contact prediction

<img src="https://colab.research.google.com/assets/colab-badge.svg">

This jupyter notebook tutorial demonstrates contact prediction with both the ESM-2 and MSA Transformer (ESM-MSA-1) models. Contact prediction is based on a logistic regression over the model's attention maps. This methodology is based on our ICLR 2021 paper, Transformer protein language models are unsupervised structure learners. (Rao et al. 2020) The MSA Transformer (ESM-MSA-1) takes a multiple sequence alignment (MSA) as input, and uses the tied row self-attention maps in the same way. See MSA Transformer. (Rao et al. 2021).

To get unsupervised attention-based contacts, call model.predict_contacts(tokens) or model(tokens, return_contacts=True).

ESMStructuralSplitDataset and self-attention contact prediction

<img src="https://colab.research.google.com/assets/colab-badge.svg">

And this jupyter notebook tutorial shows how to load and index the ESMStructuralSplitDataset, and computes the self-attention map unsupervised contact predictions using ESM-2.

Available Models and Datasets <a name="available"></a>

Pre-trained Models <a name="available-models"></a>

Here is a chronological list of the released models and the paper they were introduced in:

ESM Structural Split Dataset <a name="available-esmssd"></a>

This is a five-fold cross validation dataset of protein domain structures that can be used to measure generalization of representations across different levels of structural dissimilarity. The dataset implements structural holdouts at the family, superfamily, and fold level. The SCOPe database is used to classify domains. Independently for each level of structural hold-out, the domains are split into 5 equal sets, i.e. five sets of folds, superfamilies, or families. This ensures that for each of the five partitions, structures having the same classification do not appear in both the train and test sets. For a given classification level each structure appears in a test set once, so that in the cross validation experiment each of the structures will be evaluated exactly once.

The dataset provides 3d coordinates, distance maps, and secondary structure labels. For further details on the construction of the dataset see Rives et al. 2019 Appendix A.10.

This jupyter notebook tutorial shows how to load and index the ESMStructuralSplitDataset.

ESMStructuralSplitDataset, upon initializing, will download splits and pkl. We also provide msas for each of the domains. The data can be directly downloaded below.

Pre-training Dataset Split <a name="available-pretraining-split"></a>

The split files establishing which UniRef50 clusters were used as held-out evaluation set for pre-training in Rives et al. 2019 and Rao et al. 2021 can be found here:

• UniRef50 IDs of evaluation set: 3.016 M clusters
• UniRef100 IDs of evaluation set: 13.745 M proteins, expanding the same UniRef50 clusters.

These files only contain only the UniRef50 IDs and UniRef100 IDs corresponding to the UniRef database, 2018-03 release which is released by the UniProt Consortium under a Creative Commons Attribution (CC BY 4.0) License.

Comparison to related works <a name="perf_related"></a>

Comparison to related protein language models on structure prediction tasks.

• All contact numbers are the top-L,LR precision metric, where long range means sequence separation of at least 24 residues
• For unsupervised contact prediction, a sparse linear combination of the attention heads is used to directly predict protein contacts, fitted with logistic regression on 20 structures. For more details on the method, see Rao et al. 2020.
• For structure prediction, an AlphaFold2 structure module is trained directly from the frozen language model embeddings. For more details on the method, see Lin et al. 2022.
• Direct coupling analysis methods (Gremlin, mfDCA, Psicov) and ESM-MSA-1 use the trRosetta MSAs, while other methods predict from single sequence.

Much of this code builds on the fairseq sequence modeling framework. We use fairseq internally for our protein language modeling research. We highly recommend trying it out if you'd like to pre-train protein language models from scratch.

Additionally, if you would like to use the variant prediction benchmark from Meier et al. (2021), we provide a bibtex file with citations for all data in ./examples/variant-prediction/mutation_data.bib. You can cite each paper individually, or add all citations in bulk using the LaTeX command:
