Penicilopepsin (EC 3.4.23.20, peptidaza A, Penicillium janthinellum aspartinska proteinaza, kiselinska proteaza A, Penicillium citrinum kiselinska proteinaza, Penicillium ciklopium kiselinska proteinaza, Penicillium expansum kiselinska proteinaza, Penicillium janthinellum kiselinska proteinaza, Penicillium expansum aspartinska proteinaza, Penicillium aspartinska proteinaza, Penicillium caseicolum aspartinska proteinaza, Penicillium roqueforti kiselinska proteinaza, Penicillium duponti aspartinska proteinaza, Penicillium citrinum aspartinska proteinaza) je enzim.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju

Hidroliza proteina sa širokom specifičnošću, sličnom pepsinu A. Postoji preferencija za hidrofobne ostatke u P1 i P1', ali takođe dolazi do razlaganja Gly20-Glu u B lancu insulina.

Ovaj enzim je prisutan u gljivi Penicillium janthinellum.
