IUBMB Enzyme Nomenclature


Accepted name: vibriolysin

Reaction: Preferential cleavage of bonds with bulky hydrophobic groups in P2 and P1'. Phe at P1' is the most favoured residue, which distinguished this enzyme from thermolysin

Other names: Aeromonas proteolytica neutral proteinase; aeromonolysin

Comments: Thermostable enzyme from Vibrio proteolyticus (formerly Aeromonas proteolytica). Specificity related to, but distinct from, those of thermolysin and bacillolysin [1]. A zinc metallopeptidase In family M4 (thermolysin family). Formerly included in EC
