    Functioni

    Involved in the oxidative degradation of abscisic acid, but not in the isomerization of the produced 8'-hydroxyabscisic acid (8'-OH-ABA) to (-)-phaseic acid (PA). Involved in the control of postgermination growth.3 Publications

    Catalytic activityi

    +-abscisate + NADPH + O2 = 8'-hydroxyabscisate + NADP+ + H2O.

    Cofactori
