liver ribonucleic acid level liver gamma-glutamyltransferase mRNA level 2013-11-22T16:12:03Z BRENDA:EC2.3.2.2 CMO:0001921 JSmith Measurement of the amount of messenger ribonucleic acid (mRNA) which specifically codes for the amino acid sequence of the enzyme gamma-glutamyltranspeptidase (GGT) in a specified sample of liver. GGT catalyzes the transfer of the gamma-glutamyl moiety of glutathione to an acceptor that may be an amino acid, a peptide or water, and plays a key role in the gamma-glutamyl cycle, a pathway for the synthesis and degradation of glutathione and drug and xenobiotic detoxification. clinical_measurement_ontology liver GGTP mRNA level liver gamma-glutamyltranspeptidase mRNA level
