Arginine racemization by coupled catabolic and anabolic dehydrogenases.

Proceedings of the National Academy of Sciences of the United States of America - 20 Jan 2009

Li Congran, Lu Chung-Dar

Abstract excerpt

D-amino acids exist in living organisms as specialized components of many different machineries. Biosynthesis of D-amino acids from racemization of predominant L-enantiomers is catalyzed by a single enzyme. Here, we report the finding of a novel 2-component amino acid racemase for D-to-L inversion in D-arginine metabolism of Pseudomonas aeruginosa. From DNA microarray analysis, the putative dauBAR operon (for...
