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.

Quality

Crude

Unit Definition

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.

Exposure to organophosphorus toxicants (OP) can have chronic adverse effects that are not explained by inhibition of acetylcholinesterase, the cause of acute OP toxicity. We therefore hypothesized that OP-induced chronic illness is initiated by the formation of organophosphorus adducts on

Gamma-glutamyltranspeptidase (gammaGT), a member of the N-terminal nucleophile hydrolase superfamily, initiates extracellular glutathione reclamation by cleaving the gamma-glutamyl amide bond of the tripeptide. This protein is translated as an inactive proenzyme that undergoes autoprocessing to become an active enzyme. The

The metabolic pathway of tetrodotoxin (TTX), a powerful and specific voltage-gated sodium channel blocker, has not been well-clarified either in TTX-poisoned patients or in puffer fish. 4-S-CysteinylTTX (4-CysTTX) was isolated from the liver of the puffer fish, Fugu pardalis, as

Some amino acids and peptides, which have low solubility in water, become much more soluble following gamma-glutamylation. Compounds become more stable in the blood stream with gamma-glutamylation. Several gamma-glutamyl compounds are known to have favorable physiological effects on mammals. Gamma-glutamylation
