The cDNA coding for the precursor protein of rat liver mitochondrial vitamin D3 25-hydroxylase, cytochrome P450LMT25, was expressed under the control of the yeast alcohol dehydrogenase I promoter and terminator in Saccharomyces cerevisiae AH22 cells. The transformed yeast cells produced a P450LMT25 protein with an almost similar apparent molecular weight as compared with that of the authentic mature enzyme. The expression level of the P450LMT25 hemoprotein was about 5 x 10(4) molecules per cell as determined by reduced CO-difference spectra. The mitochondrial fraction prepared from the transformed yeast cells exhibited both 25-hydroxylase activity toward 1 alpha-hydroxyvitamin D3 and 27-hydroxylase activity toward 5 beta-cholestane-3 alpha, 7 alpha, 12 alpha-triol in a reconstituted system containing bovine adrenodoxin and NADPH-adrenodoxin reductase.
