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.
