Histolysin (EC 3.4.22.35, histolysin, Entamoeba histolytica cysteine proteinase, amebapain, Entamoeba histolytica cysteine protease, Entamoeba histolytica neutral thiol proteinase) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction

Hydrolysis of proteins, including basement membrane collagen and azocasein. Preferential cleavage: Arg-Arg- in small molecule substrates including Z-Arg-Arg-!NHMec

This enzyme is present in the protozoan, Entamoeba histolytica.
