ID   1.14.19.73
DE   (S)-nandinine synthase.
AN   CYP719A3.
CA   (S)-scoulerine + O2 + reduced [NADPH--hemoprotein reductase] = (S)-
CA   nandinine + H(+) + 2 H2O + oxidized [NADPH--hemoprotein reductase].
CC   -!- A cytochrome P450 (heme-thiolate) enzyme found in plants.
CC   -!- The enzyme catalyzes an oxidative reaction that does not incorporate
CC       oxygen into the product.
CC   -!- Forms the methylenedioxy bridge of the protoberberine alkaloid (S)-
CC       nandinine by the oxidative ring closure of adjacent phenolic and
CC       methoxy groups of (S)-scoulerine. cf. EC 1.14.19.65, which catalyzes
CC       a similar reaction at the other side of the (S)-scoulerine molecule,
CC       forming (S)-cheilanthifoline.
CC   -!- Formerly EC 1.14.21.12.
