IntEnz Enzyme Nomenclature
EC 3.4.17.11

Names

Accepted name:
glutamate carboxypeptidase
Other names:
N-pteroyl-L-glutamate hydrolase
carboxypeptidase G
carboxypeptidase G1
carboxypeptidase G2
glutamyl carboxypeptidase
Systematic name:

Reaction

Cofactor

Comments:

A zinc enzyme produced by pseudomonads, Flavobacterium sp. and Acinetobacter sp. Its ability to hydrolyse pteroyl-L-glutamate (folic acid) has led to its use as a folate-depleting, antitumour agent. Type example of peptidase family M20.
