3.4.24.36

Accepted name:

leishmanolysin

Reaction:

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-

Other name(s):

promastigote surface endopeptidase; glycoprotein gp63; Leishmania metalloproteinase; surface acid proteinase; promastigote surface protease

Comments:

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
