3" deamino 3" oxonicotianamine reductase

In enzymology, a 3"-deamino-3"-oxonicotianamine reductase (EC 1.1.1.285) is an enzyme that catalyzes the chemical reaction

2'-deoxymugineic acid + NAD(P)⁺ ⇌ 3"-deamino-3"-oxonicotianamine + NAD(P)H + H⁺

The 3 substrates of this enzyme are 2'-deoxymugineic acid, NAD⁺, and NADP⁺, whereas its 4 products are 3''-deamino-3''-oxonicotianamine, NADH, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is 2'-deoxymugineic acid:NAD(P)⁺ 3-oxidoreductase.
