Biopython: Computational Molecular Biology in Python

Overview

Biopython is a comprehensive set of freely available Python tools for biological computation. It provides functionality for sequence manipulation, file I/O, database access, structural bioinformatics, phylogenetics, and many other bioinformatics tasks. The current version is Biopython 1.87, which supports Python 3 and requires NumPy.

Version note (1.78+): The command-line application wrappers in Bio.Blast.Applications (Ncbiblastn/p/x...Commandline, NcbimakeblastdbCommandline) and Bio.Align.Applications (ClustalOmegaCommandline, MuscleCommandline) were deprecated in 1.78 and removed — they no longer import. Call BLAST+/aligner executables via subprocess instead (see references/blast.md and references/alignment.md). Bio.pairwise2 is deprecated; use Bio.Align.PairwiseAligner.

When to Use This Skill

Use this skill when:

  • Working with biological sequences (DNA, RNA, or protein)
  • Reading, writing, or converting biological file formats (FASTA, GenBank, FASTQ, PDB, mmCIF, etc.)
  • Accessing NCBI databases (GenBank, PubMed, Protein, Gene, etc.) via Entrez
  • Running BLAST searches or parsing BLAST results
  • Performing sequence alignments (pairwise or multiple sequence alignments)
  • Analyzing protein structures from PDB files
  • Creating, manipulating, or visualizing phylogenetic trees
  • Finding sequence motifs or analyzing motif patterns
  • Calculating sequence statistics (GC content, molecular weight, melting temperature, etc.)
  • Performing structural bioinformatics tasks
  • Working with population genetics data
  • Any other computational molecular biology task

Core Capabilities

Biopython is organized into modular sub-packages, each addressing specific bioinformatics domains:

  1. Sequence Handling - Bio.Seq and Bio.SeqIO for sequence manipulation and file I/O
  2. Alignment Analysis - Bio.Align and Bio.AlignIO for pairwise and multiple sequence alignments
  3. Database Access - Bio.Entrez for programmatic access to NCBI databases
  4. BLAST Operations - Bio.Blast for running and parsing BLAST searches
  5. Structural Bioinformatics - Bio.PDB for working with 3D protein structures
  6. Phylogenetics - Bio.Phylo for phylogenetic tree manipulation and visualization
  7. Advanced Features - Motifs, population genetics, sequence utilities, and more

Installation and Setup

Install Biopython (requires Python 3 and NumPy). On this machine, prefer running scripts with uv run:

# Ad-hoc: run a script with Biopython available, no venv to manage
uv run --with biopython script.py

# Or add it to a project
uv add biopython

For NCBI database access, always set your email address (required by NCBI):

from Bio import Entrez
Entrez.email = "your.email@example.com"

# Optional: API key for higher rate limits (10 req/s instead of 3 req/s)
Entrez.api_key = "your_api_key_here"

General Workflow Guidelines

Reading Documentation

When a user asks about a specific Biopython task:

  1. Identify the relevant module based on the task description
  2. Read the appropriate reference file using the Read tool
  3. Extract relevant code patterns and adapt them to the user's specific needs
  4. Combine multiple modules when the task requires it

Example search patterns for reference files:

# Find information about specific functions
grep -n "SeqIO.parse" references/sequence_io.md

# Find examples of specific tasks
grep -n "BLAST" references/blast.md

# Find information about specific concepts
grep -n "alignment" references/alignment.md
Writing Biopython Code

Follow these principles when writing Biopython code:

  1. Import modules explicitly

    from Bio import SeqIO, Entrez
from Bio.Seq import Seq

  2. Set Entrez email when using NCBI databases

    Entrez.email = "your.email@example.com"

  3. Use appropriate file formats - Check which format best suits the task

    # Common formats: "fasta", "genbank", "fastq", "clustal", "phylip"

  4. Handle files properly - Close handles after use or use context managers

    with open("file.fasta") as handle:
    records = SeqIO.parse(handle, "fasta")

  5. Use iterators for large files - Avoid loading everything into memory

    for record in SeqIO.parse("large_file.fasta", "fasta"):
    # Process one record at a time

  6. Handle errors gracefully - Network operations and file parsing can fail

    try:
    handle = Entrez.efetch(db="nucleotide", id=accession)
except HTTPError as e:
    print(f"Error: {e}")

Common Patterns

Pattern 1: Fetch Sequence from GenBank
from Bio import Entrez, SeqIO

Entrez.email = "your.email@example.com"

# Fetch sequence
handle = Entrez.efetch(db="nucleotide", id="EU490707", rettype="gb", retmode="text")
record = SeqIO.read(handle, "genbank")
handle.close()

print(f"Description: {record.description}")
print(f"Sequence length: {len(record.seq)}")
Pattern 2: Sequence Analysis Pipeline
from Bio import SeqIO
from Bio.SeqUtils import gc_fraction

for record in SeqIO.parse("sequences.fasta", "fasta"):
    # Calculate statistics
    gc = gc_fraction(record.seq)
    length = len(record.seq)

    # Find ORFs, translate, etc.
    protein = record.seq.translate()

    print(f"{record.id}: {length} bp, GC={gc:.2%}")
Pattern 3: BLAST and Fetch Top Hits
from Bio.Blast import NCBIWWW, NCBIXML
from Bio import Entrez, SeqIO

Entrez.email = "your.email@example.com"

# Run BLAST
result_handle = NCBIWWW.qblast("blastn", "nt", sequence)
blast_record = NCBIXML.read(result_handle)

# Get top hit accessions
accessions = [aln.accession for aln in blast_record.alignments[:5]]

# Fetch sequences
for acc in accessions:
    handle = Entrez.efetch(db="nucleotide", id=acc, rettype="fasta", retmode="text")
    record = SeqIO.read(handle, "fasta")
    handle.close()
    print(f">{record.description}")
Pattern 4: Build Phylogenetic Tree from Sequences
from Bio import AlignIO, Phylo
from Bio.Phylo.TreeConstruction import DistanceCalculator, DistanceTreeConstructor

# Read alignment
alignment = AlignIO.read("alignment.fasta", "fasta")

# Calculate distances
calculator = DistanceCalculator("identity")
dm = calculator.get_distance(alignment)
