| | |
| In [[enzymology]], a '''(+)-abscisic acid 8'-hydroxylase''' ({{EC number|1.14.13.93}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
| |
| | |
| :(+)-abscisate + NADPH + H<sup>+</sup> + O<sub>2</sub> <math>\rightleftharpoons</math> 8'-hydroxyabscisate + NADP<sup>+</sup> + H<sub>2</sub>O
| |
| | |
| The four [[substrate (biochemistry)|substrates]] of this enzyme are (+)-[[abscisic acid|abscisate]], [[nicotinamide adenine dinucleotide phosphate|NADPH]], [[hydrogen ion|H<sup>+</sup>]], and [[oxygen|O<sub>2</sub>]], whereas its three [[product (chemistry)|products]] are 8'-hydroxy-[[abscisic acid|abscisate]], [[nicotinamide adenine dinucleotide phosphate|NADP<sup>+</sup>]], and [[water|H<sub>2</sub>O]].
| |
| | |
| This enzyme belongs to the family of [[oxidoreductase]]s, to be specific those acting on paired donors, with O<sub>2</sub> as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O<sub>2</sub> with NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor. This enzyme participates in [[carotenoid]] [[biosynthesis]].

| | |
| == Nomenclature ==
| |
| | |
| The systematic name of this enzyme class is '''abscisate,NADPH:oxygen oxidoreductase (8'-hydroxylating)'''. Other names in common use include
| |
| * (+)-ABA 8'-hydroxylase and
| |
| * ABA 8'-hydroxylase.
