Polyporopepsin, also called Polyporus aspartic proteinase, Irpex lacteus aspartic proteinase or Irpex lacteus carboxyl proteinase B, is an enzyme found in the fungus Irpex lacteus.[1][2] It catalyses the following chemical reaction:
- Milk clotting activity, broad specificity, but fails to cleave Leu15-Tyr or Tyr16-Leu of insulin B chain.
Irpex lacteus is a basidiomycete also known as Polyporus tulipiferae.
