- The Arabidopsis cytochrome P450 CYP707A encodes ABA 8 . . . - PubMed
ABA 8'-hydroxylase was shown to be a cytochrome P450 (P450); however, its corresponding gene had not been identified Through phylogenetic and DNA microarray analyses during seed imbibition, the candidate genes for this enzyme were narrowed down from 272 Arabidopsis P450 genes
- Abscisic Acid 8′-Hydroxylase Is a Cytochrome P450 Monooxygenase
Abscisic acid (ABA) 8′-hydroxylase catalyzes the first step in the oxidative degradation of (+)-ABA The development of a robust in vitro assay has now permitted detailed examination and characterization of this enzyme
- Arabidopsis CYP707As Encode (+)-Abscisic Acid 8′-Hydroxylase, a Key . . .
The hydroxylation at the 8′-position of ABA is known as the key step of ABA catabolism, and this reaction is catalyzed by ABA 8′-hydroxylase, a cytochrome P450 Here, we demonstrate CYP707A s as the P450 responsible for the 8′-hydroxylation of (+)-ABA
- (PDF) The Arabidopsis cytochrome P450 CYP707A encodes ABA 8 . . .
ABA 8'-hydroxylase was shown to be a cytochrome P450 (P450); however, its corresponding gene had not been identified Through phylogenetic and DNA microarray analyses during seed imbibition,
- Characterization of Cytochromes P450 Involved in ABA Catabolism - J-STAGE
The hydroxylation at the 8'-position of abscisic acid (ABA) has been known as the key step of ABA catabolism, and this reaction is catalyzed by cytochromes P450 (CYPs or P450s) Here, we demonstrate CYP707A genes as the P450 responsible for the 8'-hydroxylation of (+)-ABA
- Formation and breakdown of ABA: Trends in Plant Science - Cell Press
The major pathway for ABA breakdown is via the cytochrome P450 enzyme ABA 8′-hydroxylase, which produces 8′-hydroxy ABA that cyclizes to phaseic acid (PA), which is then further reduced by phaseic acid reductase to dihydrophaseic acid
- Abscisic acid 8-hydroxylase is a cytochrome P450 monooxygenase
Abscisic acid (ABA) 8'-hydroxylase catalyzes the first step in the oxidative degradation of (+)-ABA The development of a robust in vitro assay has now permitted detailed examination and characterization of this enzyme
- The Arabidopsis cytochrome P450 CYP707A encodes ABA 8′‐hydroxylases . . .
ABA 8′‐hydroxylase was shown to be a cytochrome P450 (P450); however, its corresponding gene had not been identified Through phylogenetic and DNA microarray analyses during seed imbibition, the candidate genes for this enzyme were narrowed down from 272 Arabidopsis P450 genes
