Germacrene A alcohol dehydrogenase (EC 1.1.1.314) is an enzyme with systematic name germacra-1(10),4,11(13)-trien-12-ol:NADP+ oxidoreductase.[1][2] This enzyme catalyses the following chemical reaction
- germacra-1(10),4,11(13)-trien-12-ol + 2 NADP+ + H2O [math]\displaystyle{ \rightleftharpoons }[/math] germacra-1(10),4,11(13)-trien-12-oate + 2 NADPH + 3 H+ (overall reaction)
- (1a) germacra-1(10),4,11(13)-trien-12-ol + NADP+ [math]\displaystyle{ \rightleftharpoons }[/math] germacra-1(10),4,11(13)-trien-12-al + NADPH + H+
- (1b) germacra-1(10),4,11(13)-trien-12-al + NADP+ + H2O [math]\displaystyle{ \rightleftharpoons }[/math] germacra-1(10),4,11(13)-trien-12-oate + NADPH + 2 H+
In Lactuca sativa this enzyme is a multifunctional enzyme with EC 1.14.13.123.
