Popis

General description

Gamma-Glutamyltranspeptidase is a heterodimeric enzyme and belongs to the superfamily of N-terminal nucleophile hydrolases.

Application

Gamma-glutamyltranspeptidase from equine kidney has been used:

• to identify the formation of 4-S-Cysteinyltetrodotoxin in the liver of Fugu pardalis
• as a standard to determine the activity of gamma-glutamyltransferase from human B-cell lymphoma cell lysates
• to hydrolyze isopeptides to study its effects on tubulin aggregation

Biochem/physiol Actions

Gamma-Glutamyltranspeptidase participates in glutathione metabolism and it catalyzes the cleavage of gamma-glutamyl compounds, such as glutathione. It also plays a role in the transfer of gamma-glutamyl moiety to amino acids and peptides.

Analysis Note

Crude

Other Notes

One unit will liberate 1.0 μmole of p-nitroaniline from L-γ-glutamyl-p-nitroanilide per min at pH 8.5 at 25°C.
