L-arginine:NAD(P)+ oxidoreductase (deaminating)
The enzyme, which has been isolated from the bacterium Pseudomonas aeruginosa PAO1, forms with EC 1.4.99.6, D-arginine dehydrogenase, a two-enzyme complex involved in the racemization of D- and L-arginine.
strains with a lesion at DauA or DauB genes fail to use D-arginine as sole carbon source. Growth complementation of an L-arginine auxotroph by D-arginine is abolished by a lesion at DauA or DauB. Presence of D-arginine induces L-arginine-specific genes in the parental strain PAO1 but not in its dauA or dauB mutants. DauA catalyzes oxidative deamination of D-arginine into 2-ketoarginine 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
