IUBMB Enzyme Nomenclature


Accepted name: 8-hydroxygeraniol dehydrogenase

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+

Other name(s): 8-hydroxygeraniol oxidoreductase; CYP76B10; G10H; CrG10H; SmG10H; acyclic monoterpene primary alcohol:NADP+ oxidoreductase

Systematic name: (6E)-8-hydroxygeraniol:NADP+ oxidoreductase

Comments: Contains Zn2+. The enzyme catalyses the oxidation of (6E)-8-hydroxygeraniol to (6E)-8-oxogeranial via either (6E)-8-hydroxygeranial or (6E)-8-oxogeraniol. Also acts on geraniol, nerol and citronellol. May be identical to EC geraniol dehydrogenase. The recommended numbering of geraniol gives 8-hydroxygeraniol as the substrate rather than 10-hydroxygeraniol as used by references 1 and 2. See prenol nomenclature Pr-1.
