EC 3.4.24.31

Names

Accepted name:
mycolysin
Other names:
Streptomyces griseus neutral proteinase
SGNPI
actinase E
pronase component
Systematic name:
-

Reaction

Cofactor

Comments:

From Streptomyces griseus, S. naraensis, and S. cacaoi. Specificity similar to that of thermolysin, but much more sensitive to inhibition by mercaptoacetyl-Phe-Leu. Little structural similarity to other bacterial metalloendopeptidases. Type example of peptidase family M5. Formerly included in EC 3.4.24.4.
