一般描述

γ-谷氨酰转肽酶是一种异二聚酶,属于N端亲核水解酶超家族。

应用

来自马肾的γ-谷氨酰转肽酶已用于:

  • 鉴定河豚肝脏中4-S-半胱氨酸河豚毒素的形成
  • 作为标准品,用于测定人B细胞淋巴瘤细胞裂解物的γ -谷氨酰转移酶的活性
  • 解异肽,以研究其对微管蛋白聚集的影响

生化/生理作用

γ-谷氨酰转肽酶参与谷胱甘肽代谢,可以催化γ -谷氨酰化合物的裂解,如谷胱甘肽。它还对γ -谷氨酰基向氨基酸和多肽的转移发挥着作用。

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

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

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
