IUBMB Enzyme Nomenclature

EC 3.4.24.29

Accepted name: aureolysin

Reaction: Cleavage of insulin B chain with specificity similar to that of thermolysin, preferring hydrophobic P1' residue. Activates the glutamyl endopeptidase (EC 3.4.21.19) of Staphylococcus aureus

Other names: Staphylococcus aureus neutral proteinase; Staphylococcus aureus neutral protease

Comments: A metalloenzyme from Staphylococcus aureus earlier confused with staphylokinase (a non-enzymatic activator of plasminogen). Formerly EC 3.4.99.22 and included in EC 3.4.24.4
