Metabolite Identification
Common NameAlpha-N-Phenylacetyl-L-glutamine
DescriptionPhenylacetylglutamine is a product formed by the conjugation of phenylacetate and glutamine. Technically it is the amino acid acetylation product of phenylacetate (or phenylbutyrate after beta-oxidation). Phenylacetylglutamine is a normal constituent of human urine, but other mammals including the dog, cat, rat, monkey, sheep and horse do not excrete this compound. Phenylacetyl CoA and glutamine react to form phenylacetyl glutamine and Coenzyme A. The enzyme (Glutamine N-acetyl transferase) that catalyzes this reaction has been purified from human liver mitochondria and shown to be a distinct polypeptide species from glycine-N-acyltransferase. Phenylacetylglutamine is a major nitrogenous metabolite that accumulates in uremia. (PMID: 2791363 ; PMID: 8972626 ). It has been shown that over 50% of urine phenylacetylglutamine may be derived from kidney conjugation of free plasma phenylacetic acid and/or from the kidney's preferential filtration of conjugated phenylacetic acid (PMID: 6420430 ). In enzymology, a glutamine N-phenylacetyltransferase (EC 2.3.1.14) is an enzyme that catalyzes the chemical reaction. phenylacetyl-CoA + L-glutamine CoA + alpha-N-phenylacetyl-L-glutamine. Thus, the two substrates of this enzyme are phenylacetyl-CoA and L-glutamine, whereas its two products are CoA and alpha-N-phenylacetyl-L-glutamine.(Wikipedia).
