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 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+ germacra-1(10),4,11(13)-trien-12-al + NADPH + H+
(1b) germacra-1(10),4,11(13)-trien-12-al + NADP+ + H2O germacra-1(10),4,11(13)-trien-12-oate + NADPH + 2 H+

In Lactuca sativa this enzyme is a mutifunctional enzyme with EC 1.14.13.123.
