Well-established quality management system.
Reaction
a 14α-methylsteroid + 3 [reduced NADPH—hemoprotein reductase] + 3 O2 = a Δ14-steroid + formate + 3 [oxidized NADPH—hemoprotein reductase] + 4 H2O (overall reaction)
(1a) a 14α-methylsteroid + [reduced NADPH—hemoprotein reductase] + O2 = a 14α-hydroxymethylsteroid + [oxidized NADPH—hemoprotein reductase] + H2O
(1b) a 14α-hydroxysteroid + [reduced NADPH—hemoprotein reductase] + O2 = a 14α-formylsteroid + [oxidized NADPH—hemoprotein reductase] + 2 H2O
(1c) a 14α-formylsteroid + [reduced NADPH—hemoprotein reductase] + O2 = a Δ14-steroid + formate + [oxidized NADPH—hemoprotein reductase] + H2O
Systematic Name
sterol,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (14-methyl cleaving)
Function
This cytochrome P-450 (heme-thiolate) enzyme acts on a range of steroids with a 14α-methyl group, such as obtusifoliol and lanosterol. The enzyme catalyses a hydroxylation and a reduction of the 14α-methyl group, followed by a second hydroxylation, resulting in the elimination of formate and formation of a 14(15) double bond.
Other name
obtusufoliol 14-demethylase; lanosterol 14-demethylase; lanosterol 14α-demethylase; sterol 14-demethylase; CYP51 (gene name); ERG11 (gene name)
