Chymosin.
based on mapping to UniProt Q9GK11
Broad specificity similar to that of pepsin A. Clots milk by cleavage of a single 104-Ser-Phe-|-Met-Ala-107 bond in kappa-chain of casein.
-!- Neonatal gastric enzyme with high milk clotting and weak general proteolytic activity, formed from prochymosin. -!- Found among mammals with postnatal uptake of immunoglobins. -!- Belongs to peptidase family A1. -!- Formerly EC 3.4.4.3.
