Enums

AminoAcid

The 20 standard amino acids plus Unknown, with integer discriminants matching the conventional protein-ML encoding (Ala=0 … Unknown=20).

Constants

ALPHABET

Functions

aa1to_int

aa3to1

Convert a 3-letter amino acid code to a 1-letter code.

int_to_aa1

Convert an integer index (0–20) to a 1-letter amino acid code.
