3D Structures of Chymotrypsin
Updated on 23-November-2022
The Chy precursor is the inactive chymotrypsinogen (Chygen) which gets cleaved 3 times by trypsin and chymotrypsin losing a 4 amino acid long peptide to become the active Chy. γ-Chy is a covalent acyl adduct of α-Chy. δ-Chy results when Chygen is cleaved only twice.
