EC 1.14.19.65 Details
show Brenda entryEC number
1.14.19.65
Accepted name
(S)-cheilanthifoline synthase
Reaction
(S)-scoulerine + [reduced NADPH—hemoprotein reductase] + O2 = (S)-cheilanthifoline + [oxidized NADPH—hemoprotein reductase] + 2 H2O
Other name(s)
CYP719A14 (gene name),
(S)-scoulerine oxidase (methylenedioxy-bridge-forming) (ambiguous)
Systematic name
(S)-scoulerine,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase [(S)-cheilanthifoline-forming]
CAS registry number
138791-27-2
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.
