title: Expression of cytochrome P-450d by Saccharomyces cerevisiae.
abstract: Rat liver microsomal cytochrome P-450d was abundantly expressed in the yeast Saccharomyces cerevisiae by using a yeast-Escherichia coli shuttle vector consisting of rat liver P-450d cDNA and yeast acid phosphatase promoter. The expressed cytochrome P-450d was immunologically crossed with rat liver P-450d. The hydroxylase activity of estra-1,3,5(10)-triene-3, 17 beta-diol was 11 nmol/min per nmol P-450d, which is comparable to that reported previously for rat liver P-450d. The expressed P-450d content was nearlyt 1% of total yeast protein as estimated from immunoblotting, hydroxylase activity and optical absorpton of the reduced CO form.
