ESM:进化尺度建模 是做什么的?

概述

ESM 提供蛋白质语言模型,用于理解、生成和设计蛋白质。此技能适用于当前的 EvolutionaryScale/Biohub 工作流:用于生成式设计的 ESM3、用于表示学习和嵌入的 ESMC、托管的 Forge/Biohub 推理,以及 ESMFold2 全原子结构预测。

核心能力

1. 使用 ESM3 进行蛋白质序列生成

使用多模态生成建模,生成具有所需特性的新型蛋白质序列。

何时使用:

  • 设计具有特定功能特性的蛋白质
  • 补全部分蛋白质序列
  • 生成现有蛋白质的变体
  • 创建具有所需结构特征的蛋白质

基本用法:

from esm.models.esm3 import ESM3
from esm.sdk.api import ESM3InferenceClient, ESMProtein, GenerationConfig

# 接受 Hugging Face 上的许可后加载本地开放权重。
model: ESM3InferenceClient = ESM3.from_pretrained("esm3-open").to("cuda")

# 创建蛋白质提示
protein = ESMProtein(sequence="MPRT___KEND")  # '_' 代表掩码位置

# 生成补全
protein = model.generate(protein, GenerationConfig(track="sequence", num_steps=8))
print(protein.sequence)

通过 Forge API 远程/云端使用:

import os
import esm
from esm.sdk.api import ESMProtein, GenerationConfig

# 与本地 ESM3 接口相同;令牌来自 ESM_API_KEY(请参阅身份验证)
model = esm.sdk.client("esm3-medium-2024-08", token=os.environ["ESM_API_KEY"])

# 生成
protein = model.generate(protein, GenerationConfig(track="sequence", num_steps=8))

有关详细的 ESM3 模型规格、高级生成配置和多模态提示示例,请参阅 references/esm3-api.md。

2. 结构预测和逆折叠

使用 ESM3 的结构轨道进行基于序列的结构预测或基于结构的序列设计(逆折叠)。

结构预测:

from esm.sdk.api import ESM3InferenceClient, ESMProtein, GenerationConfig

# 从序列预测结构
protein = ESMProtein(sequence="MPRTKEINDAGLIVHSP...")
protein_with_structure = model.generate(
    protein,
    GenerationConfig(track="structure", num_steps=protein.sequence.count("_"))
)

# 访问预测结构
coordinates = protein_with_structure.coordinates  # 3D 坐标
pdb_string = protein_with_structure.to_pdb()

逆折叠(从结构到序列):

# 为目标结构设计序列
protein_with_structure = ESMProtein.from_pdb("target_structure.pdb")
protein_with_structure.sequence = None  # 移除序列

# 生成能够折叠到此结构的序列
designed_protein = model.generate(
    protein_with_structure,
    GenerationConfig(track="sequence", num_steps=50, temperature=0.7)
)

3. 使用 ESM C 进行蛋白质嵌入

为下游任务(如功能预测、分类或相似性分析)生成高质量的嵌入。

何时使用:

  • 为机器学习提取蛋白质表示
  • 计算序列相似性
  • 特征提取用于蛋白质分类
  • 蛋白质相关任务的迁移学习

基本用法:

from esm.models.esmc import ESMC
from esm.sdk.api import ESMProtein, LogitsConfig

# 加载 ESM C 模型
model = ESMC.from_pretrained("esmc_300m").to("cuda")

# 获取嵌入
protein = ESMProtein(sequence="MPRTKEINDAGLIVHSP...")
protein_tensor = model.encode(protein)
logits_output = model.logits(
    protein_tensor,
    LogitsConfig(sequence=True, return_embeddings=True),
)
embeddings = logits_output.embeddings

批量处理:

# 编码多个蛋白质
proteins = [
    ESMProtein(sequence="MPRTKEIND..."),
    ESMProtein(sequence="AGLIVHSPQ..."),
    ESMProtein(sequence="KTEFLNDGR...")
]

embeddings_list = [
    model.logits(
        model.encode(p),
        LogitsConfig(sequence=True, return_embeddings=True),
    ).embeddings
    for p in proteins
]

有关 ESM C 模型详细信息、效率比较和高级嵌入策略,请参阅 references/esm-c-api.md。

4. 功能条件化和注释

使用 ESM3 的功能轨道,生成带有特定功能注释的蛋白质或从序列预测功能。

功能条件化生成:

from esm.sdk.api import ESMProtein, FunctionAnnotation, GenerationConfig

# 创建具有所需功能的蛋白质
protein = ESMProtein(
    sequence="_" * 200,  # 生成 200 个残基的蛋白质
    function_annotations=[
        FunctionAnnotation(label="fluorescent_protein", start=50, end=150)
    ]
)

# 生成带有指定功能的序列
functional_protein = model.generate(
    protein,
    GenerationConfig(track="sequence", num_steps=200)
)

5. 思维链生成

使用 ESM3 的思维链生成方法迭代优化蛋白质设计。

from esm.sdk.api import GenerationConfig

# 多步骤优化
protein = ESMProtein(sequence="MPRT" + "_" * 100 + "KEND")

# 步骤 1:生成初始结构
config = GenerationConfig(track="structure", num_steps=50)
protein = model.generate(protein, config)

# 步骤 2:基于结构优化序列
config = GenerationConfig(track="sequence", num_steps=50, temperature=0.5)
protein = model.generate(protein, config)

# 步骤 3:预测功能
config = GenerationConfig(track="function", num_steps=20)
protein = model.generate(protein, config)

6. 使用 Forge API 进行批量处理

使用 Forge 的异步方法高效处理多个蛋白质。

import os
import asyncio
import esm
from esm.sdk.api import ESMProtein, GenerationConfig

client = esm.sdk.client("esm3-medium-2024-08", token=os.environ["ESM_API_KEY"])

# 异步批量处理
async def batch_generate(proteins_list):
    tasks = [
        client.async_generate(protein, GenerationConfig(track="sequence"))
        for protein in proteins_list
    ]
    return await asyncio.gather(*tasks)

# 执行
proteins = [ESMProtein(sequence=f"MPRT{'_' * 50}KEND") for _ in range(10)]
results = asyncio.run(batch_generate(proteins))

有关 Forge API 文档、身份验证、速率限制和批量处理模式的详细信息,请参阅 references/forge-api.md。

模型选择指南

ESM3 模型(生成式):

  • esm3-open (1.4B) - 开放权重,接受 Hugging Face 许可后本地使用
  • esm3-medium-2024-08 (7B) - 在质量和速度之间取得最佳平衡(仅限 Forge)
  • esm3-large-2024-03 (98B) - 最高质量,速度较慢(仅限 Forge)

ESM C 模型(嵌入):

  • esmc_300m / esmc-300m-2024-12 (30 层) - 轻量级、快速推理(开放权重,本地)
  • esmc_600m / esmc-600m-2024-12 (36 层) - 平衡性能(开放权重,本地)
  • esmc-6b-2024-12 (80 层) - 最高质量(Forge API;本地 6B 权重需要 Forge 或 SageMaker)

本地的 ESMC.from_pretrained() 示例使用下划线别名(esmc_300m、esmc_600m)。托管的 API 客户端使用带日期的模型 ID,例如 esmc-600m-2024-12。

选择标准:

  • 本地开发/测试: 使用 esm3-open 或 esmc_300m
  • 生产质量: 通过 Forge 使用 esm3-medium-2024-08
  • 最高精度: 通过 Forge 使用 esm3-large-2024-03 或 esmc-6b-2024-12
  • 高吞吐量: 使用 Forge 或 Biohub API,并设置明确的异步并发限制
  • 成本优化: 使用较小的模型,实施缓存策略

安装

从 PyPI(esm 在 PyPI 上 by EvolutionaryScale)安装。当前的 PyPI 版本:3.2.3(2025 年 10 月 14 日)。需要 Python >=3.12,<3.13。

基本安装:

uv pip install "esm==3.2.3"

包含 Flash Attention(推荐在 NVIDIA GPU 上加速推理):

uv pip install "esm==3.2.3"
uv pip install flash-attn --no-build-isolation

Forge 客户端随 esm 包一起提供 - 无需为 ESM3 或 ESMC Forge 推理额外安装。

身份验证

Forge API 访问需要 API 密钥。切勿将令牌硬编码在脚本中或提交到版本控制。

  1. 检查环境中是否已设置 ESM_API_KEY。
  2. 如果没有,检查本地 .env 文件中是否包含 ESM_API_KEY(仅此密钥,不要加载不相关的密钥)。
  3. 如果仍然缺失,请在 Biohub 开发者控制台(用于 Biohub API)或 Forge(用于传统的 Forge 托管的 ESM3/ESMC 访问)中创建一个密钥。
import os

token = os.environ["ESM_API_KEY"]  # 如果未设置,将引发 KeyError

当省略 token 时,esm.sdk.client() 会自动读取 ESM_API_KEY。请将端点 URL 固定为受信任的主机,例如 https://forge.evolutionaryscale.ai 或 https://biohub.ai;不要接受来自不受信任用户输入的 API 主机。

Biohub 平台: EvolutionaryScale 和 Forge 现在通过 biohub.ai 展示当前托管的模型。SDK 类名可能仍会引用“Forge”。有关 ESMFold2 和 Biohub 特定设置,请参阅 references/biohub-platform.md。

对于嵌入任务:

  • 在可能的情况下批量处理序列以提高效率
  • 缓存嵌入以进行重复分析
  • 计算相似性时标准化嵌入
  • 根据下游任务要求,使用适当的模型大小

对于生产部署:

  • 使用 Forge API 以获得可扩展性和最新模型
  • 为 API 调用实现错误处理和重试逻辑
  • 监控令牌使用情况并实现速率限制
  • 考虑将 AWS SageMaker 部署用于专用基础设施

Query the CZ CELLxGENE Census programmatically for versioned public single-cell and spatial transcriptomics data. Use when you need population-scale cell metadata, gene expression slices, Census summary counts, source H5AD URIs/downloads, embeddings, spatial Census data, or reference atlas comparisons across organisms, tissues, diseases, assays, and cell types. For analyzing your own local single-cell data use scanpy, anndata, or scvi-tools.
