N-Acetyl-D-methionine may be used as a substrate to identify, differentiate and characterized N-acylamino acid racemase(s) and N-acyl-D-amino acid amidohydrolase(s).
European journal of biochemistry, 269(19), 4868-4878 (2002-10-02)
An N-acyl-d-amino acid amidohydrolase (N-D-AAase) was identified in cell extracts of a strain, Iso1, isolated from an environment containing N-acetyl-d-methionine. The bacterium was classified as Variovorax paradoxus by phylogenetic analysis. The gene was cloned and sequenced. The gene consisted of

N-acylamino acid racemase (NAAAR) catalyzes the racemization of N-acylamino acids and can be used in concert with an aminoacylase to produce enantiopure alpha-amino acids, a process that has potential industrial applications. Here we have cloned and characterized an NAAAR homologue

A bulky platinum triamine complex, [Pt(Me(5)dien)(NO(3))]NO(3) (Me(5)dien=N,N,N',N',N''-pentamethyldiethylenetriamine) has been prepared and reacted in D(2)O with N-acetylmethionine (N-AcMet) and guanosine 5'-monophosphate (5'-GMP); the reactions have been studied using (1)H NMR spectroscopy. Reaction with 5'-GMP leads to two rotamers of [Pt(Me(5)dien)(5'-GMP-N7)](+). Reaction

Hippurate is known to be synthesized from benzoate and glycine in the liver and kidney. It takes part in renal ammoniagenesis by modulating the activity of gamma-glutamyl transpeptidase (gamma GT). Due to its chemical structure, however, hippurate might also serve
Various commercial lyophilized and immobilized preparations of lipase A from Candida antarctica (CAL-A) were studied for their ability to catalyze the hydrolysis of amide bonds in N-acylated alpha-amino acids, 3-butanamidobutanoic acid (beta-amino acid) and its ethyl ester. The activity toward
