Enzyme Information
| 3.4.23.20 |
Penicillopepsin.
based on mapping to UniProt P00798
Hydrolysis of proteins with broad specificity similar to that of pepsin A, preferring hydrophobic residues at P1 and P1', but also cleaving 20-Gly-|-Glu-21 in the B chain of insulin. Clots milk, and activates trypsinogen.
-!- From the imperfect fungus Penicillium janthinellum. -!- Closely related enzymes have been isolated from P.roqueforti and P.duponti. -!- Belongs to peptidase family A1. -!- Formerly EC 3.4.4.17, EC 3.4.23.6 and EC 3.4.23.7.
