本酶催化的反应为Ent-Kaur-16-En-19-Oate + 3 NADPH + 3 H+ + 3 O2 = Gibberellin A12 + 3 NADP+ + 4 H2O (Overall Reaction);;(1a) Ent-Kaur-16-En-19-Oate + NADPH + H+ + O2 = Ent-7alpha-Hydroxykaur-16-En-19-Oate + NADP+ + H2O;;(1b) Ent-7alpha-Hydroxykaur-16-En-19-Oate + NADPH + H+ + O2 = Gibberellin A12 Aldehyde + NADP+ + 2 H2O;;(1c) Gibberellin A12 Aldehyde + NADPH + H+ + O2 = Gibberellin A12 + NADP+ + H2O，系统名称为Ent-Kaur-16-En-19-Oate,NADPH:oxygen Oxidoreductase (Hydroxylating)，需要细胞色素P-450。催化对映-贝壳杉烯酸（ent-kaurenoic acid）的三次连续氧化。第二步包括B环收缩，形成赤霉素（gibbane）骨架。在南瓜（Cucurbita maxima）中还会形成对映-6α,7α-二羟基贝壳杉-16-烯-19-酸。
