EC 1.14.14.104     
Accepted name: vinorine hydroxylase
Reaction: vinorine + [reduced NADPH—hemoprotein reductase] + O2 = vomilenine + [oxidized NADPH—hemoprotein reductase] + H2O
Systematic name: vinorine,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (21α-hydroxylating)
Comments: A cytochrome P-450 (heme-thiolate) protein from the plant Rauvolfia serpentina. Forms a stage in the biosynthesis of the indole alkaloid ajmaline.
