IUBMB Enzyme Nomenclature


Accepted name: L-arginine dehydrogenase

Reaction: L-arginine + H2O + NAD(P)+ = 5-guanidino-2-oxopentanoate + NH3 + NAD(P)H + H+

Other name(s): dauB (gene name); anabolic L-arginine dehydrogenase

Systematic name: L-arginine:NAD(P)+ oxidoreductase (deaminating)

Comments: The enzyme, which has been isolated from the bacterium Pseudomonas aeruginosa PAO1, forms with EC, D-arginine dehydrogenase, a two-enzyme complex involved in the racemization of D- and L-arginine.
