obsolete ent-7-alpha-hydroxykaurenoate oxidase activity (obsolete GO:0051778)
OBSOLETE. Catalysis of the reaction: ent-7-alpha-hydroxykaurenoate + NADPH + H+ + O2 = gibberellin 12-aldehyde + NADP+ + 2 H2O. This is the second of three successive reactions resulting in the oxidation of ent-kaurenoate (ent-kaurenoic acid) to gibberellin 12 (GA12).
