| Comment(s) |
|---|
- This cytochrome P450 (heme-thiolate) enzyme acts on a range of
steroids with a 14alpha-methyl group, such as obtusifoliol and
lanosterol.
- The enzyme catalyzes a hydroxylation and a reduction of the 14alpha-
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.
