Title
Cytochrome P450 promiscuity leads to a bifurcating biosynthetic pathway for tanshinones.
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor
A cytochrome P-450 (heme-thiolate) protein isolated from the plant Salvia miltiorrhiza (danshen). The enzyme also oxidizes 11-hydroxyferruginol to 11-hydroxysugiol. It also oxidizes at C-12 of ferruginol (EC 1.14.14.60 ferruginol monooxygenase).
