Designation of enzyme activity of glycine-N-acyltransferase family genes and depression of glycine-N-acyltransferase in human hepatocellular carcinoma.
Matsuo M., Terai K., Kameda N., Matsumoto A., Kurokawa Y., Funase Y., Nishikawa K., Sugaya N., Hiruta N., Kishimoto T.
The human glycine-N-acyltransferase (hGLYAT) gene and two related-genes (GLYATL1 and GLYATL2) were isolated. Human GLYAT, GLYATL1, and GLYATL2 cDNAs were isolated and shown to encode polypeptides of 295, 302, and 294 amino acids, respectively. GLYAT catalyzes glycine-N-acyltransfer reaction with b ... >> More
The human glycine-N-acyltransferase (hGLYAT) gene and two related-genes (GLYATL1 and GLYATL2) were isolated. Human GLYAT, GLYATL1, and GLYATL2 cDNAs were isolated and shown to encode polypeptides of 295, 302, and 294 amino acids, respectively. GLYAT catalyzes glycine-N-acyltransfer reaction with benzoyl-CoA acting as a typical aralkyl transferase, while GLYATL1 catalyzed glutamine-N-acyltransfer reaction with phenylacetyl-CoA as an arylacetyl transferase. GLYAT was shown to be expressed specifically in the liver and kidney, and the cellular localization of GLYAT protein was restricted to the mitochondria. Interestingly, labeling using highly affinity purified anti-GLYAT antibody revealed that GLYAT expression was suppressed in all hepatocellular carcinomas, but not in other liver diseases. hGLYAT repression in cancerous cells in the liver was controlled at the transcriptional level. hGLYAT is a good candidate as a novel marker of hepatocellular carcinoma and may be a key molecule in the transition between differentiation and carcinogenesis of liver cells. << Less

Benzoyl-coenzyme A:glycine N-acyltransferase and phenylacetyl-coenzyme A:glycine N-acyltransferase from bovine liver mitochondria. Purification and characterization.
Nandi D.L., Lucas S.V., Webster L.T. Jr.
Two closely related acyl-CoA:amino acid N-acyl-transferases were purified to near-homogeneity from preparations of bovine liver mitochondria. Each enzyme consisted of a single polypeptide chain with a molecular weight near 33,000. One transferase was specific for benzoyl-CoA, salicyl-CoA, and cert ... >> More
Two closely related acyl-CoA:amino acid N-acyl-transferases were purified to near-homogeneity from preparations of bovine liver mitochondria. Each enzyme consisted of a single polypeptide chain with a molecular weight near 33,000. One transferase was specific for benzoyl-CoA, salicyl-CoA, and certain short straight and branched chain fatty acyl-CoA esters as substrates while the other enzyme specifically used either phenylacetyl-CoA or indoleacetyl-CoA. Acyl-CoA substrates for one transferase inhibited the other. Glycine was the preferred acyl acceptor for both enzymes but either L-asparagine or L-glutamine also served. Peptide products for each transferase were identified by mass spectrometry. Enzymatic cleavage of acyl-CoA was stoichiometric with release of thiol and formation of peptide product. Apparent Km values were low for the preferred acyl-CoA substrates relative to the amino acid acceptors (10(-5) M range compared to greater than 10(-3) M). Both enzymes were inhibited by high nonphysiological concentrations of certain divalent cations (Mg2+, Ni2+, and Zn2+). In contrast to benzoyltransferase, phenylacetyltransferase was sensitive to inhibition by either 10(-4) M 5,5'-dithiobis(2-nitrobenzoate) or 10(-5) M p-chloromercuribenzoate; 10(-4) M phenylacetyl-CoA partially protected phenylacetyltransferase against 5,5'-dithiobis(2-nitrobenzoate) inactivation but 10(-1) M glycine did not. For activity, phenylacetyltransferase required addition of certain monovalent cations (K+, Rb+, Na+, Li+, Cs+, or (NH4)+) to the assay system but benzoyltransferase did not. Preliminary kinetic studies of both transferases were consistent with a sequential reaction mechanism in which the acyl-CoA substrate adds to the enzyme first, glycine adds before CoA leaves, and the peptide product dissociates last. << Less

Identification of separate acyl- CoA:glycine and acyl-CoA:L-glutamine N-acyltransferase activities in mitochondrial fractions from liver of rhesus monkey and man.
Webster L.T., Siddiqui U.A., Lucas S.V., Strong J.M., Mieyal J.J.

The conjugation of glycine to benzoates and the conjugation of L-glutamine to certain arylacetates are catalyzed by two different acyl-CoA:amino acid N-acyltransferases which can be purified separately from liver mitochondrial fractions of either rhesus monkey or man. In both species, one transferase is specific for glycine and the other for L-glutamine. The glycine enzyme utilizes either butyryl-CoA or benzoyl-CoA as acyl donors while the glutamine enzyme uses either phenylacetyl-CoA or indoleacetyl-CoA. Acyl-CoA substrates for one transferase do not serve as substrates for the other. Additional studies with the monkey liver enzymes revealed that acyl-CoA substrates for one transferase inhibit the other, that the apparent Km value is low (10(-6) to 10(-5) M range) for the preferred acyl-CoA substrate as compared to the amino acid acceptor (greater than 10(-2) M) and that both transferases have a molecular weight of approximately 24,000. Hippuric acid and either phenylacetylglutamine or indoleacetylglutamine were characterized as the products formed by the separate enzymes. << Less

Purification to homogeneity of mitochondrial acyl CoA:glycine N-acyltransferase from human liver.

Mitochondrial acyl CoA:glycine N-acyl transferase (ACGNAT) was purified to homogeneity from adult human liver. It was found to be a monomer of 30 kD, having a pI of 6.8. ACGNAT retained 47% of enzymatic activity at 100 mM NaCl concentration, whereas 21% of the activity was retained with KCl and 32% with K3PO4 at 100 mM concentration as compared to the control. The stability studies revealed no change in activity at 4 degrees C for up to 72 h, 25 degrees C for 4 h and at 37 degrees C for 1 h. The Km values of human ACGNAT for benzoyl CoA, salicyl CoA, isovaleryl CoA and octanoyl CoA were 57.9, 83.7, 124 and 198 mM, respectively, and the corresponding Vmax values were 17.1, 10.1, 7.64 and 3.3 mumol/min/mg protein. The availability of pure human ACGNAT would help in studying the molecular genetics and structural biology of this protein which is important in the detoxification of various endogenous and xenobiotic acyl CoA's. << Less
