Abstract |
The moss Physcomitrella patens produces both ent-kaurene and ent-kaurenoic acid, which are intermediates of gibberellin biosynthesis in flowering plants. The CYP701 superfamily of cytochrome P450s functions as ent-kaurene oxidases in the biosynthesis of ent-kaurenoic acid. A candidate gene encoding ent-kaurene oxidase in P. patens, CYP701B1, was cloned and heterologously expressed in yeast to examine enzyme activities in vitro. The recombinant CYP701B1 protein catalyzed the oxidation reaction from ent-kaurene to ent-kaurenoic acid. CYP701B1 activity was highly resistant to the ent-kaurene oxidase inhibitor uniconazole-P (IC(50) 64 μM), even though the activity of Arabidopsis ent-kaurene oxidase (CYP701A3) was sensitive (IC(50) 0.26 μM). |
