IUBMB Enzyme Nomenclature


Accepted name: glutamate carboxypeptidase

Reaction: Release of C-terminal glutamate residues from a wide range of N-acylating moieties, including peptidyl, aminoacyl, benzoyl, benzyloxycarbonyl, folyl and pteroyl groups

Other names: carboxypeptidase G; carboxypeptidase G1; carboxypeptidase G2; glutamyl carboxypeptidase; N-pteroyl-L-glutamate hydrolase

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
