氨基酸γ—谷酰基转移酶(GGT)催化谷胱甘肽和其他γ—谷酰基化合物上的谷酰基转移到各种氨基酸和肽受体上。该酶虽不参与药物代谢,但血清GGT含量升高一般认为是肝胆疾病诊断的一个良好指标。成年大鼠GGT活力低,在化学致肝癌过程中GGT可明显墳加。肾脏是GGT最重要的来 The amino acid gamma-glutamyl transferase (GGT) catalyzes the transfer of glutamyl groups on glutathione and other gamma-glutamyl compounds to various amino acid and peptide receptors. Although the enzyme is not involved in drug metabolism, serum GGT levels are generally considered to be a good indicator of the diagnosis of hepatobiliary disease. GGT activity of adult rats is low, GGT can be significantly increased in the process of chemical liver cancer. Kidney is the most important GGT
