malfunction
utilization of L-Ala, L-Trp, D-Ala, D-His, D-Phe, D-Ser, D-Thr, and D-Val as sole nitrogen sources is abolished in the dadA mutant
metabolism
D-amino acid dehydrogenase activity of broad substrate specificity
physiological function
D-to-L inversion in D-arginine metabolism requires both D-arginine dehydrogenase DauA and NAD(P)H-dependent anabolic L-arginine dehydrogenase DauB. DauA catalyzes oxidative deamination of D-arginine into 2-oxoarginine and ammonia, and DauB is able to use 2-ketoarginine and ammonia as substrates and convert them into L-arginine in the presence of NADPH or NADH. DauA and DauB are coupled catabolic and anabolic dehydrogenases that enable D-arginine utilization through L-arginine catabolic pathways
physiological function
involved in catabolism of several D-amino acids
physiological function
the enzyme is highly expressed by Pseudomonas aeruginosa within the cystic fibrosis lung, and it is required for optimal production of hydrogen cyanide by some cystic fibrosis-adapted isolates. The enzyme is required for optimal production of pyocyanin, pyoverdine, and rhamnolipid by cystic fibrosis-adapted and non-cystic fibrosis-adapted isolates of Pseudomonas aeruginosa. In addition, the enzyme is required for optimal production of alginate, biofilm formation, and virulence of a cystic fibrosis-adapted isolated of Pseudomonas aeruginosa
