KEGG   ENZYME: 3.4.24.31
Entry
EC 3.4.24.31                Enzyme                                 
Name
mycolysin;
pronase component;
Streptomyces griseus neutral proteinase;
actinase E;
SGNPI
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Metalloendopeptidases
Reaction(IUBMB)
Preferential cleavage of bonds with hydrophobic residues in P1'
Comment
The enzyme has been characterized from the bacteria Streptomyces griseus, Streptomyces naraensis, and Streptomyces cacaoi. Specificity is similar to that of thermolysin, but the enzyme is much more sensitive to inhibition by sulfanylacetyl-Phe-Leu. Little structural similarity to other bacterial metalloendopeptidases. Type example of peptidase family M5.
History
EC 3.4.24.31 created 1972 as EC 3.4.24.4, part transferred 1992 to EC 3.4.24.31
