BioServices 是做什么的?

概述

BioServices 是一个 Python 包,提供对大约 40 个生物信息学网络服务和数据库的程序化访问。你可以在 Python 工作流中检索生物数据、执行跨数据库查询、映射标识符、分析序列以及集成多个生物资源。该包透明地处理 REST 和 SOAP/WSDL 协议。

版本说明: 示例针对 bioservices 1.16.0(PyPI,2026年3月)。需要 Python 3.9–3.12。2022年中期的 UniProt REST 更改(bioservices ≥1.10)主要影响表格 columns 名称——如果解析失败,请参考上游 _legacy_names。ChEMBL 包装器在1.6.0版本(2018年 API)发生变更;请使用 get_similarity、get_substructure、get_molecule 代替1.6之前的旧方法名。

何时使用该技能

该技能适用于以下场景:

  • 从 UniProt、PDB、Pfam 检索蛋白质序列、注释或结构
  • 通过 KEGG 或 Reactome 分析代谢通路和基因功能
  • 搜索化合物数据库(ChEBI、ChEMBL、PubChem)以获取化学信息
  • 在不同生物数据库之间转换标识符(KEGG↔UniProt、化合物 ID)
  • 运行序列相似性搜索(BLAST、MUSCLE 比对)
  • 查询基因本体术语(QuickGO、GO 注释)
  • 访问蛋白质-蛋白质相互作用数据(PSICQUIC、IntactComplex)
  • 挖掘基因组数据(BioMart、ArrayExpress、ENA)
  • 在单一工作流中集成多个生物信息学资源的数据

核心功能

1. 蛋白质分析

检索蛋白质信息、序列和功能注释:

from bioservices import UniProt

u = UniProt(verbose=False)

# 按名称搜索蛋白质
results = u.search("ZAP70_HUMAN", frmt="tab", columns="id,genes,organism")

# 检索 FASTA 序列
sequence = u.retrieve("P43403", "fasta")

# 在数据库之间映射标识符
kegg_ids = u.mapping(fr="UniProtKB_AC-ID", to="KEGG", query="P43403")

关键方法:

  • search():使用灵活的搜索词查询 UniProt
  • retrieve():以多种格式(FASTA、XML、表格)获取蛋白质条目
  • mapping():在数据库之间转换标识符

参考:references/services_reference.md 获取完整的 UniProt API 详情。

2. 通路发现与分析

访问基因和生物的 KEGG 通路信息:

from bioservices import KEGG

k = KEGG()
k.organism = "hsa"  # 设置为人类

# 搜索生物
k.lookfor_organism("droso")  # 查找果蝇物种

# 按名称查找通路
k.lookfor_pathway("B cell")  # 返回匹配的通路 ID

# 获取包含特定基因的通路
pathways = k.get_pathway_by_gene("7535", "hsa")  # ZAP70 基因

# 检索并解析通路数据
data = k.get("hsa04660")
parsed = k.parse(data)

# 提取通路相互作用
interactions = k.parse_kgml_pathway("hsa04660")
relations = interactions['relations']  # 蛋白质-蛋白质相互作用

# 转换为简单交互格式
sif_data = k.pathway2sif("hsa04660")

关键方法:

  • lookfor_organism()、lookfor_pathway():按名称搜索
  • get_pathway_by_gene():查找包含基因的通路
  • parse_kgml_pathway():提取结构化通路数据
  • pathway2sif():获取蛋白质相互作用网络

参考:references/workflow_patterns.md 获取完整的通路分析工作流。

3. 化合物数据库搜索

跨多个数据库搜索和交叉引用化合物:

from bioservices import KEGG, UniChem

k = KEGG()

# 按名称搜索化合物
results = k.find("compound", "Geldanamycin")  # 返回 cpd:C11222

# 获取包含数据库链接的化合物信息
compound_info = k.get("cpd:C11222")  # 包含 ChEBI 链接

# 使用 UniChem 交叉引用 KEGG → ChEMBL
u = UniChem()
chembl_id = u.get_compound_id_from_kegg("C11222")  # 返回 CHEMBL278315

**版本警告:**bioservices 1.16.0 已移除按来源的 get_compound_id_from_* 辅助方法——请先检查 hasattr(u, "get_compound_id_from_kegg"),否则使用当前的 UniChem API(u.get_compounds(compound, source_type) 并读取 res["compounds"][0]["sources"])。ChEMBL 查询遵循相同规则:使用 get_molecule,而不是 1.6 之前的 get_compound_by_chemblId。

常见工作流:

  1. 在 KEGG 中按名称搜索化合物
  2. 提取 KEGG 化合物 ID
  3. 使用 UniChem 进行 KEGG → ChEMBL 映射
  4. ChEBI ID 通常包含在 KEGG 条目中

参考:references/identifier_mapping.md 获取完整的跨数据库映射指南。

4. 序列分析

运行 BLAST 搜索和序列比对。NCBI 需要联系邮箱——建议使用 NCBI_EMAIL 环境变量(与 BioPython Entrez 和其他仓库技能相同约定):

import os
from bioservices import NCBIblast

s = NCBIblast(verbose=False)
email = os.environ["NCBI_EMAIL"]  # 运行前设置:export [email protected]

# 针对 UniProtKB 运行 BLASTP
jobid = s.run(
    program="blastp",
    sequence=protein_sequence,
    stype="protein",
    database="uniprotkb",
    email=email,
)

# 检查作业状态并检索结果
s.getStatus(jobid)
results = s.getResult(jobid, "out")

注意: BLAST 作业是异步的。检索结果前请检查状态。

5. 标识符映射

在不同生物数据库之间转换标识符:

from bioservices import UniProt, KEGG

# UniProt 映射(支持多种数据库对)
u = UniProt()
results = u.mapping(
    fr="UniProtKB_AC-ID",  # 源数据库
    to="KEGG",              # 目标数据库
    query="P43403"          # 要转换的标识符
)

# KEGG 基因 ID → UniProt
kegg_to_uniprot = u.mapping(fr="KEGG", to="UniProtKB_AC-ID", query="hsa:7535")

# 对于化合物,使用 UniChem
from bioservices import UniChem
u = UniChem()
chembl_from_kegg = u.get_compound_id_from_kegg("C11222")

支持的映射(UniProt):

  • UniProtKB ↔ KEGG
  • UniProtKB ↔ Ensembl
  • UniProtKB ↔ PDB
  • UniProtKB ↔ RefSeq
  • 以及更多(参见 references/identifier_mapping.md)

6. 基因本体查询

访问 GO 术语和注释:

from bioservices import QuickGO

g = QuickGO(verbose=False)

# 检索 GO 术语信息
term_info = g.Term("GO:0003824", frmt="obo")

# 搜索注释
annotations = g.Annotation(protein="P43403", format="tsv")

7. 蛋白质-蛋白质相互作用

通过 PSICQUIC 查询相互作用数据库。PSICQUIC 并非每个版本都提供——在 1.16.0 中缺失——因此请防御性导入,并在缺失时回退到 IntactComplex、OmniPath 或 STRING:

from bioservices import PSICQUIC

s = PSICQUIC(verbose=False)

# 查询特定数据库(例如 MINT)
interactions = s.query("mint", "ZAP70 AND species:9606")

# 列出可用的相互作用数据库
databases = s.activeDBs

可用数据库: MINT、IntAct、BioGRID、DIP 等 30 多个。

多服务集成工作流

BioServices 擅长组合多个服务进行综合分析。常见的集成模式:

完整的蛋白质分析流程

执行完整的蛋白质表征工作流:

export [email protected]
python scripts/protein_analysis_workflow.py ZAP70_HUMAN
# 或者如果未设置 NCBI_EMAIL,将邮箱作为可选的第二个参数传递
python scripts/protein_analysis_workflow.py ZAP70_HUMAN [email protected]

该脚本演示了:

  1. UniProt 搜索蛋白质条目
  2. FASTA 序列检索
  3. BLAST 相似性搜索
  4. KEGG 通路发现
  5. PSICQUIC 相互作用映射

通路网络分析

分析某个生物的所有通路:

python scripts/pathway_analysis.py hsa output_directory/

提取并分析:

  • 该生物的所有通路 ID
  • 每个通路的蛋白质-蛋白质相互作用
  • 相互作用类型分布
  • 导出为 CSV/SIF 格式

跨数据库化合物搜索

跨数据库映射化合物标识符:

python scripts/compound_cross_reference.py Geldanamycin

检索:

  • KEGG 化合物 ID
  • ChEBI 标识符
  • ChEMBL 标识符
  • 基本化合物属性

批量标识符转换

一次转换多个标识符:

python scripts/batch_id_converter.py input_ids.txt --from UniProtKB_AC-ID --to KEGG

最佳实践

输出格式处理

不同服务以多种格式返回数据:

  • XML:使用 BeautifulSoup 解析(大多数 SOAP 服务)
  • 制表符分隔(TSV):Pandas DataFrame 处理表格数据
  • 字典/JSON:直接 Python 操作
  • FASTA:与 BioPython 集成进行序列分析

速率限制和详细程度

控制 API 请求行为:

from bioservices import KEGG

k = KEGG(verbose=False)  # 抑制 HTTP 请求详情
k.TIMEOUT = 30  # 调整慢速连接的超时

错误处理

在 try-except 块中包装服务调用:

try:
    results = u.search("ambiguous_query")
    if results:
        # 处理结果
        pass
except Exception as e:
    print(f"搜索失败: {e}")

生物代码

使用标准生物缩写:

  • hsa:智人(人类)
  • mmu:小家鼠(小鼠)
  • dme:黑腹果蝇(果蝇)
  • sce:酿酒酵母(酵母)

列出所有生物:k.list("organism") 或 k.organismIds

与其他工具的集成

BioServices 与以下工具配合良好:

  • BioPython:对检索到的 FASTA 数据进行序列分析
  • Pandas:处理表格数据
  • PyMOL:3D 结构可视化(检索 PDB ID)
  • NetworkX:通路相互作用网络分析
  • Galaxy:为工作流平台定制工具包装器

biopython

Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.

bulk-rnaseq

End-to-end bulk RNA-seq orchestrator — takes raw FASTQ reads through QC and trimming (FastQC, fastp/Trim Galore), alignment and quantification (STAR, Salmon, featureCounts), assembles a gene-level counts matrix, then hands off to differential expression (pydeseq2), pathway/GSEA enrichment (pathway-enrichment), and publication figures (scientific-visualization). Use whenever the user has bulk RNA-seq reads or quant output and wants a complete, reproducible differential-expression workflow — e.g.

cellxgene-census

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.

cirq

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.

citation-management

Comprehensive citation management for academic research. Search OpenAlex, PubMed, and Google Scholar for papers, extract accurate metadata, validate citations, and generate properly formatted BibTeX entries. This skill should be used when you need to find papers, verify citation information, convert DOIs to BibTeX, or ensure reference accuracy in scientific writing.

clinical-decision-support

Prepare and validate research-only clinical decision-support evaluation, evidence-profile, cohort, survival, biomarker/model, privacy, and governance artifacts. Use for aggregate or synthetic research documentation and traceability—not patient care or live clinical operation.

clinical-reports

Create safety-bounded draft structures and run local deterministic checks for clinical case, diagnostic, trial, safety, and aggregate research reports. Use only with synthetic, de-identified, or aggregate inputs and verified source-fact manifests; every output requires qualified review.
