Polyporopepsin (EC 3.4.23.29, Polyporus aspartic proteinase, Irpex lacteus aspartic proteinase, Irpex lacteus carboxyl proteinase B) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction
- Milk clotting activity, broad specificity, but fails to cleave Leu15-Tyr or Tyr16-Leu of insulin B chain
This enzyme is isolated from the basidiomycete Polyporus tulipiferae.
