Glossary: ferruginol = abieta-8,11,13-trien-12-ol
sugiol = 12-hydroxyabieta-8,11,13-trien-7-one
Other name(s): CYP76AH3
Systematic name: ferruginol,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (sugiol forming)
Comments: 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).
