Monooxygenase that oxidizes ferruginol to produce sugiol (PubMed:26682704). Oxidizes ferruginol at C-12 to produce 11-hydroxyferruginol (PubMed:26682704). Can oxidize 11-hydroxyferruginol to 11-hydroxysugiol (PubMed:26682704). These products are intermediates in tanshinone biosynthesis (PubMed:26682704). ferruginol + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] = 2 H(+) + 3 H2O + 2 oxidized [NADPH--hemoprotein reductase] + sugiol ferruginol + O2 + reduced [NADPH--hemoprotein reductase] = 11-hydroxyferruginol + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] 11-hydroxyferruginol + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] = 11-hydroxysugiol + 2 H(+) + 3 H2O + 2 oxidized [NADPH--hemoprotein reductase] Secondary metabolite biosynthesis; terpenoid biosynthesis. Expressed in roots. Belongs to the cytochrome P450 family.
