1.14.14.69
Accepted name
ent-cassadiene hydroxylase
Reaction
ent-cassa-12,15-diene + 3 [reduced NADPH—hemoprotein reductase] + 3 O2 = ent-3β-hydroxycassa-12,15-dien-2-one + 3 [oxidized NADPH—hemoprotein reductase] + 4 H2O (overall reaction);;(1a) ent-cassa-12,15-diene + [reduced NADPH—hemoprotein reductase] + O2 = ent-cassa-12,15-dien-2β-ol + [oxidized NADPH—hemoprotein reductase] + H2O;;(1b) ent-cassa-12,15-dien-2β-ol + [reduced NADPH—hemoprotein reductase] + O2 = ent-cassa-12,15-dien-2-one + [oxidized NADPH—hemoprotein reductase] + 2 H2O;;(1b′) ent-cassa-12,15-dien-2β-ol + [reduced NADPH—hemoprotein reductase] + O2 = ent-cassa-12,15-diene-2β,3β-diol + [oxidized NADPH—hemoprotein reductase] + H2O;;(1c) ent-cassa-12,15-dien-2-one + [reduced NADPH—hemoprotein reductase] + O2 = ent-3β-hydroxycassa-12,15-dien-2-one + [oxidized NADPH—hemoprotein reductase] + H2O;;(1c′) ent-cassa-12,15-diene-2β,3β-diol + [reduced NADPH—hemoprotein reductase] + O2 = ent-3β-hydroxycassa-12,15-dien-2-one + [oxidized NADPH—hemoprotein reductase] + 2 H2O
Other name(s)
CYP71Z7
Systematic name
ent-cassa-12,15-diene,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (ent-3β-hydroxycassa-12,15-dien-2-one-forming)
Comment
A cytochrome P-450 (heme-thiolate) protein isolated from the plant Oryza sativa (rice) that is involved in phytocassanes biosynthesis. Depending on the order of activities, the enzyme may form either ent-cassa-12,15-dien-2-one or ent-cassa-12,15-diene-2β,3β-diol as an intermediate.
