It transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol (By similarity). Favors C4 dimethylated substrates, the substrate preference order is 24-methylenedihydrolanosterol > 24,25-dihydrolanosterol > lanosterol > obtusifoliol > norlanosterol.<ref>PMID:16321980</ref> [UniProtKB:P0A512] |
