Abstract

Lanosterol 14α-demethylase (cytochrome P45014DM) is a housekeeping enzyme occurring widely in eukaryotes. It is a cytochrome P450 mono-oxygenase catalyzing the conversion of lanosterol or 24,25-dihydrolanosterol (DHL) to the 14-demethylated and 14,15-desaturated derivatives by removing the 14α-methyl group (C32) as formic acid (Fig. 1) (Watkinson and Akhtar 1969; Alexander et al. 1972; Gibbons and Mitropoulos 1973; Mitropoulos et al. 1976; Aoyama and Yoshida 1978; Aoyama et al. 1984; Trzaskos et al. 1986). The 14α-demethylation is an essential reaction of steroid biosynthesis by eukaryotes, because most of the functional steroids have no 14-methyl group.
