Summary

Description

An early (1984) X-ray crystallography structure of papain, a cysteine protease enzyme found in papaya. The primarily alpha-helical L-domain is shown at left, while the beta-sheet-rich R-domain is shown at right. The catalytic residues are highlighted; cysteine (oxidized in this structure) in green and histidine in blue. A conserved disulfide bond is shown in cyan. Rendered using PyMol from PDB: 9PAP​.
