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