ENTRY EC 3.4.19.2
NAME Peptidyl-glycinamidase
Carboxyamidase
Peptidyl carboxyamidase
CLASS Hydrolases
Acting on peptide bonds (peptidases)
Omega peptidases
REACTION Cleavage of C-terminal glycinamide from polypeptides
SUBSTRATE Peptide
H2O
PRODUCT Glycine
Peptide
INHIBITOR Diisopropyl fluorophosphate
COMMENT Inactivates vasopressin and oxytocin by splitting off glycinamide.
Also cleaves ester substrates of trypsin and chymotrypsin.
Although glycinamide is by far the preferred cleaving group, other
aminoacylamides may also be released, e.g. phenylalaninamide. The
toad skin enzyme is inhibited by diisopropyl fluorophosphate.
Formerly EC 3.4.15.2.
