Acrocylindropepsin (EC 3.4.23.28, Acrocylindrium proteinase, Acrocylindrium acid proteinase) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction
- Preference for hydrophobic residues at P1 and P1'. Action on the B chain of insulin is generally similar to that of pepsin A, but it also cleaves Leu6-Cys(SO3H), Glu21-Arg and Asn3-Gln, although not Gln4-His
This enzyme is present in fungus Acrocylindrium sp.
