General annotation (Comments)

Function	Catalyzes the methyl transfer from S-adenosyl-methionine to the C-24 of zymosterol to form fecosterol.
Catalytic activity	S-adenosyl-L-methionine + 5-alpha-cholesta-8,24-dien-3-beta-ol = S-adenosyl-L-homocysteine + 24-methylene-5-alpha-cholest-8-en-3-beta-ol.
Pathway	Steroid metabolism; ergosterol biosynthesis; ergosterol from zymosterol: step 1/5.
Sequence similarities	Belongs to the methyltransferase superfamily. ERG6 family.
