I'm new to biopython & I'm trying to extract residues from specific chain of each file from a list of 316 pdb files. Eg: 1d8t has four chains A, B, C & D of which my interest is to extract just the residues of C chain. As the chain of interest differs for different files, I'm not knowing how to extract specific chain residue from each file and save it separately.
from Bio import * from Bio.PDB.PDBParser import PDBParser from Bio.PDB.Polypeptide import PPBuilder structure = PDBParser().get_structure('1d8t', '1d8t.pdb') model = structure chain = model['C'] for i in chain.get_residues(): print(i)
With the above code I was able to extract the residues of C chains not sure how to proceed for multiple files in python.
