ID 1.14.14.137 DE (+)-abscisic acid 8'-hydroxylase. AN (+)-ABA 8'-hydroxylase. AN ABA 8'-hydroxylase. AN CYP707A1. CA 2-cis-(+)-abscisate + O2 + reduced [NADPH--hemoprotein reductase] = (+)- CA 8'-hydroxyabscisate + H(+) + H2O + oxidized [NADPH--hemoprotein CA reductase]. CC -!- A cytochrome P450 (heme-thiolate) protein found in plants. CC -!- Catalyzes the first step in the oxidative degradation of abscisic CC acid and is considered to be the pivotal enzyme in controlling the CC rate of degradation of this plant hormone. CC -!- CO inhibits the reaction, but its effects can be reversed by the CC presence of blue light. CC -!- The 8'-hydroxyabscisate formed can be converted into (-)-phaseic CC acid, most probably spontaneously. CC -!- Formerly EC 1.14.13.93.
