bis_protein_structure.CROSSLINK.calculate_lys_leu_map

bis_protein_structure.CROSSLINK.calculate_lys_leu_map(chain_id, chain, residue_dict)

Generates a binary map indicating the presence of Lysine (LYS) or Leucine (LEU) residues.

Parameters:

• chain_id (str) – Chain identifier.

• chain (Bio.PDB.Chain) – Chain object from the parsed structure.

• residue_dict (dict) – Dictionary mapping chain IDs to residues and their positions.

Returns:

• residue_length (int) – Number of residues in the chain.

• lys_leu_map (numpy.ndarray) – A 2D boolean array where True indicates the presence of LYS or LEU at corresponding residue positions.
