DESCRIPTION

Also known as NQRED_PSEAE, PA1024. Catalyzes the NADH-dependent reduction of a broad spectrum of quinone substrates, generating the corresponding hydroquinones. Highly prefers NADH to NADPH as a reducing substrate. Also displays a small NADH oxidase activity. Does not exhibit nitronate monooxygenase activity; is inactive against propionate 3-nitronate, 3-nitropropionate, nitroethane, 1-nitropropane, 2-nitropropane, and the anionic forms ethylnitronate, propyl-1-nitronate, and propyl-2-nitronate. Has no azoreductase activity since it is not able to reduce the azo dye methyl red with NADH. May be required to maintain an appropriate [NAD(+)]/[NADH] ratio for the catabolism of fatty acids in P.aeruginosa PAO1. Monomer.
