CC   -!- FUNCTION: Catalyzes the 14-alpha demethylation of obtusifoliol to 4
CC       alpha-methyl-5 alpha-ergosta-8,14,24(28)-trien-3 beta-ol.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 14alpha-methyl steroid + 3 O2 + 3 reduced [NADPH--
CC         hemoprotein reductase] = a Delta(14) steroid + formate + 4 H(+) + 4
CC         H2O + 3 oxidized [NADPH--hemoprotein reductase];

CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413;
CC   -!- PATHWAY: Steroid biosynthesis; zymosterol biosynthesis; zymosterol from
CC       lanosterol: step 1/6.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
