EC 1.14.19.73 Details
show Brenda entryEC number
1.14.19.73
Accepted name
(S)-nandinine synthase
Reaction
(S)-scoulerine + [reduced NADPH—hemoprotein reductase] + O2 = (S)-nandinine + [oxidized NADPH—hemoprotein reductase] + 2 H2O
Other name(s)
CYP719A3
Systematic name
(S)-scoulerine,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase [(S)-nandinine-forming]
Comment
A cytochrome P-450 (heme-thiolate) enzyme found in plants. The enzyme catalyses an oxidative reaction that does not incorporate oxygen into the product. Forms the methylenedioxy bridge of the protoberberine alkaloid (S)-nandinine by the oxidative ring closure of adjacent phenolic and methoxy groups of (S)-scoulerine. cf. EC 1.14.19.65, (S)-cheilanthifoline synthase, which catalyses a similar reaction at the other side of the (S)-scoulerine molecule, forming (S)-cheilanthifoline.
