EC 126.96.36.199 - Leishmanolysin
IntEnz Enzyme Nomenclature
promastigote surface endopeptidase
promastigote surface protease
surface acid proteinase
- Preference for hydrophobic residues at P1 and P1' and basic residues at P2' and P3'. A model nonapeptide is cleaved at -Ala-Tyr┼Leu-Lys-Lys-.
A membrane-bound glycoprotein found on the promastigote of various species of Leishmania protozoans. Contains consensus sequence for a zinc-binding site; Z-Tyr-Leu-NHOH is a strong inhibitor. The enzyme can activate its proenzyme by cleavage of the Val100┼Val bond. An acid pH optimum is found with certain protein substrates. Type example of peptidase family M8.
