Vinorine hydroxylase (EC 1.14.14.104, Formerly EC 1.14.13.75) is an enzyme that catalyzes the chemical reaction

1. REDIRECT Template:Chemical reaction

Vinorine hydroxylase is a cytochrome P450 protein containing heme, isolated from Rauwolfia serpentina. It requires a partner cytochrome P450 reductase for functional expression. This uses nicotinamide adenine dinucleotide phosphate. The systematic name of this enzyme class is vinorine,NADPH:oxygen oxidoreductase (21alpha-hydroxylating). This enzyme is part of the biosynthetic pathway to the indole alkaloid, ajmaline.[1][2][3]
