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.
拟南芥GA3 cDNA在酵母(酿酒酵母)中表达,并检测了转化酵母细胞代谢贝壳杉烯的能力。我们通过全扫描气相色谱 - 质谱法表明,转化细胞产生贝壳杉烯酸,并证明单一酶GA3(贝壳杉烯氧化酶)催化从贝壳杉烯到贝壳杉烯酸的赤霉素生物合成的三个步骤。
