Enzyme Information

1.14.14.154
Sterol 14-alpha-demethylase.
based on mapping to UniProt Q7Z1V1
A 14-alpha-methylsteroid + 3 [reduced NADPH--hemoprotein reductase] + 3 O(2) = a Delta(14)-steroid + formate + 3 [oxidized NADPH--hemoprotein reductase] + 4 H(2)O.
-!- This cytochrome P450 (heme-thiolate) enzyme acts on a range of steroids with a 14-alpha-methyl group, such as obtusifoliol and lanosterol. -!- The enzyme catalyzes a hydroxylation and a reduction of the 14-alpha- methyl group, followed by a second hydroxylation, resulting in the elimination of formate and formation of a 14(15) double bond. -!- Formerly EC 1.14.13.70.
