Arabidopsis ent-kaurene oxidase catalyzes three steps of gibberellin biosynthesis.
نویسندگان
چکیده
The Arabidopsis GA3 cDNA was expressed in yeast (Saccharomyces cerevisiae) and the ability of the transformed yeast cells to metabolize ent-kaurene was tested. We show by full-scan gas chromatography-mass spectrometry that the transformed cells produce ent-kaurenoic acid, and demonstrate that the single enzyme GA3 (ent-kaurene oxidase) catalyzes the three steps of gibberellin biosynthesis from ent-kaurene to ent-kaurenoic acid.

An overview of gibberellin metabolism enzyme genes and their related mutants in rice.
To enhance our understanding of GA metabolism in rice (Oryza sativa), we intensively screened and identified 29 candidate genes encoding the following GA metabolic enzymes using all available rice DNA databases: ent-copalyl diphosphate synthase (CPS), ent-kaurene synthase (KS), ent-kaurene oxidase (KO), ent-kaurenoic acid oxidase (KAO), GA 20-oxidase (GA20ox), GA 3-oxidase (GA3ox), and GA 2-oxi...
متن کاملThe Arabidopsis GA1 locus encodes the cyclase ent-kaurene synthetase A of gibberellin biosynthesis.
The first committed step in the gibberellin (GA) biosynthetic pathway is the conversion of geranylgeranyl pyrophosphate (GGPP) through copalyl pyrophosphate (CPP) to ent-kaurene catalyzed by ent-kaurene synthetases A and B. The ga1 mutants of Arabidopsis are gibberellin-responsive male-sterile dwarfs. Biochemical studies indicate that biosynthesis of GAs in the ga1 mutants is blocked prior to t...
متن کاملInvestigating the evolution of cytochromes P450 involved in GA biosynthesis
Vascular plants invariably contain a class II diterpene cyclase (EC 5.5.1.x), as an entcopalyl diphosphate synthase is required for gibberellin phytohormone biosynthesis. This has provided the basis for evolution of a functionally diverse enzymatic family. A bifunctional diterpene synthase was characterized from the lycophyte Selaginella moellendorffii. The structure of its product, labda-7,13E...
متن کاملA conformationally restricted uniconazole analogue as a specific inhibitor of rice ent-kaurene oxidase, CYP701A6.
The plant growth retardant uniconazole (UNI), which has been used as an effective inhibitor of ent-kaurene oxidase (CYP701A) involved in gibberellin biosynthesis, also strongly inhibits ABA 8'-hydroxylase (CYP707A), a key enzyme in abscisic acid catabolism. Azole P450 inhibitors bind to the P450 active site by both coordinating to the heme-iron atom via an sp(2) nitrogen and interacting with su...
متن کاملOverexpression of AtCPS and AtKS in Arabidopsis confers increased ent-kaurene production but no increase in bioactive gibberellins.
The plant growth hormone gibberellin (GA) is important for many aspects of plant growth and development. Although most genes encoding enzymes at each step of the GA biosynthetic pathway have been cloned, their regulation is less well understood. To assess how up-regulation of early steps affects the biosynthetic pathway overall, we have examined transgenic Arabidopsis plants that overexpress ei...
