Physarolisin (EC 3.4.21.103, Dictyostelium discoideum aspartic proteinase, Dictyostelium discoideum aspartic proteinase E, Physarum flavicomum aspartic proteinase, Physarum polycephalum acid proteinase, Physarum aspartic proteinase, physaropepsin) is an enzyme.[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- Milk clotting activity. Preferential cleavage of Gly8-Ser in B chain of insulin most rapidly, followed by Leu11!Val, Cys(SO3H)19-Gly and Phe24-Phe.
This enzyme belongs in peptidase family S53.
