KEGG   ENZYME: 1.14.19.65
Entry
EC 1.14.19.65               Enzyme                                 
Name
(S)-cheilanthifoline synthase;
CYP719A14 (gene name);
(S)-scoulerine oxidase (methylenedioxy-bridge-forming) (ambiguous)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
Sysname
(S)-scoulerine,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase [(S)-cheilanthifoline-forming]
Reaction(IUBMB)
(S)-scoulerine + [reduced NADPH---hemoprotein reductase] + O2 = (S)-cheilanthifoline + [oxidized NADPH---hemoprotein reductase] + 2 H2O [RN:R03834]
Reaction(KEGG)
R03834
Substrate
(S)-scoulerine [CPD:C02106];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]
Product
(S)-cheilanthifoline [CPD:C05174];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]
Comment
A cytochrome P-450 (heme-thiolate) protein catalysing an oxidative reaction that does not incorporate oxygen into the product. Forms the methylenedioxy bridge of the protoberberine alkaloid cheilanthifoline by the oxidative ring closure of adjacent phenolic and methoxy groups of scoulerine. cf. EC 1.14.19.73, (S)-nandinine synthase, which catalyses a similar reaction at the other side of the (S)-scoulerine molecule, forming (S)-nandinine.
