ENZYME entry: EC 3.4.21.103
Accepted Name |
Physarolisin.
|
Alternative Name(s) |
Dictyostelium discoideum aspartic proteinase. |
Dictyostelium discoideum aspartic proteinase E. |
Physaropepsin. |
Physarum aspartic proteinase. |
Physarum flavicomum aspartic proteinase. |

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