Accepted name: germacrene A alcohol dehydrogenase

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+
