glycoprotein gp63
promastigote surface endopeptidase
promastigote surface protease
surface acid proteinase
Systematic name:

Reaction

Cofactors

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.
