Basic usage#

Let’s convert 3-letter residue codes to single-letter codes:

import molsysmt as msm

codes = ['ALA', 'CYS', 'ASP', 'GLU', 'PHE', 'GLY', 'HIS', 'ILE', 'LYS', 'LEU', 'MET', 'ASN', 'PRO', 'GLN', 'ARG', 'SER', 'THR', 'VAL', 'TRP', 'TYR']
one_letters = [msm.element.group.amino_acid.get_1_letter_code_from_name(c) for c in codes]
print('Sequence:', ''.join(one_letters))

Sequence: ACDEFGHIKLMNPQRSTVWY
