ID 3.4.21.103 DE physarolisin. AN Dictyostelium discoideum aspartic proteinase. AN Dictyostelium discoideum aspartic proteinase E. AN physaropepsin. AN Physarum aspartic proteinase. AN Physarum flavicomum aspartic proteinase. AN Physarum polycephalum acid proteinase. CA Milk clotting activity. Preferential cleavage of 8-Gly-|-Ser-9 in B chain CA of insulin most rapidly, followed by 11-Leu-|-Val-12, CA 19-Cys(SO(3)H)-|-Gly and 24-Phe-|-Phe-25. No action on Ac-Phe-Tyr(I)2. CC -!- From the slime mold Physarum polycephalum. CC -!- Is not inhibited by pepstatin, but is blocked by methyl CC 2-diazoacetamidohexanoate. CC -!- Closely similar enzymes are found in Dictyostelium discoideum and CC P.flavicomum. CC -!- Belongs to peptidase family S53. CC -!- Formerly EC 3.4.4.17, EC 3.4.23.6 and EC 3.4.23.27.
