8-Hydroxygeraniol dehydrogenase

8-hydroxygeraniol dehydrogenase (EC 1.1.1.324, 8-hydroxygeraniol oxidoreductase, CYP76B10, G10H, CrG10H, SmG10H, acyclic monoterpene primary alcohol:NADP+ oxidoreductase) is an enzyme with systematic name (6E)-8-hydroxygeraniol:NADP+ oxidoreductase.[1][2] This enzyme catalyses the following chemical reaction

(6E)-8-hydroxygeraniol + 2 NADP+ (6E)-8-oxogeranial + 2 NADPH + 2 H+ (overall reaction)
(1a) (6E)-8-hydroxygeraniol + NADP+ (6E)-8-hydroxygeranial + NADPH + H+
(1b) (6E)-8-hydroxygeraniol + NADP+ (6E)-8-oxogeraniol + NADPH + H+
(1c) (6E)-8-hydroxygeranial + NADP+ (6E)-8-oxogeranial + NADPH + H+
(1d) (6E)-8-oxogeraniol + NADP+ (6E)-8-oxogeranial + NADPH + H+
