Accepted name: ent-sandaracopimaradiene 3-hydroxylase
Reaction: ent-sandaracopimaradiene + [reduced NADPH—hemoprotein reductase] + O2 = ent-sandaracopimaradien-3β-ol + [oxidized NADPH—hemoprotein reductase] + H2O

Glossary: ent-sandaracopimaradiene = ent-13α-pimara-8(14),15-diene = (4aR,4bR,7S,10aR)-7-ethenyl-1,1,4a,7-tetramethyl-1,2,3,4,4a,4b,5,6,7,9,10,10a-dodecahydrophenanthrene
Other name(s): CYP701A; OsKOL4
Systematic name: ent-sandaracopimaradiene,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (ent-sandaracopimaradien-3β-ol-forming)
Comments: A cytochrome P-450 (heme-thiolate) protein isolated from Oryza sativa (rice). Participates in the pathway for the biosynthesis of oryzalexins, a group of related phytoalexins produced by rice. Can also use 9β-pimara-7,15-diene as substrate (cf. EC, syn-pimaradiene 3-monooxygenase).
