Enzyme Information

3.4.17.21
Glutamate carboxypeptidase II.
based on mapping to UniProt Q04609
Release of an unsubstituted, C-terminal glutamyl residue, typically from Ac-Asp-Glu or folylpoly-gamma-glutamates.
-!- Hydrolyzes alpha-peptide bonds in Ac-Asp-Glu, Asp-Glu, and Glu-Glu, but also gamma-glutamyl bonds in gamma-Glu-Glu and folylpoly-gamma- glutamates. -!- With folylpoly-gamma-glutamates, shows processive carboxypeptidase activity to produce pteroylmonoglutamate. -!- Does not hydrolyze Ac-beta-Asp-Glu. -!- Inhibited by quisqualic acid, Ac-beta-Asp-Glu, and 2-phosphonomethyl- pentanedioate. -!- The release of C-terminal glutamate from folylpoly-gamma-glutamates is also catalyzed by EC 3.4.17.11 and EC 3.4.19.9. -!- Belongs to peptidase family M28. -!- Formerly EC 3.4.19.8.
