    摘要: The expression of mitochondrial P450 in yeast is disclosed. The mitochondrial P450 includes a chimeric P450 in which a signal sequence present at the N-terminus of a mammalian mitochondrial P450 has been substituted by a signal of a yeast mitochondrial protein and a chimeric P450 in which the latter signal has been further substituted by a targeting signal sequence to microsome.An expression plasmid for producing the enzyme in a large scale, a recombinant yeast strain carrying the expression plasmid, a process for producing the enzyme by the use of the recombinant yeast, and a process for producing 5.beta.-cholestane-3.alpha., 7.alpha., 12.alpha., 27-tetrol, 25-hydroxyvitamin D.sub.3 and 1.alpha.,25-dihydroxyvitamin D.sub.3 are also disclosed.

    摘要: There is disclosed a method for evaluation of the safety of a chemical compound, which includes the steps of: (a) reacting a chemical compound with recombinant yeast cells expressing, or in other words producing, human cytochrome P450 molecular species P450 1A2, P450 2C9, P450 2E1 and P450 3A4 together with a yeast NADPH-P450 reductase, which may be in the form of a fused enzyme with each of said human cytochrome P450 molecular species, or with the cell free extracts of the yeast cells; and (b) analyzing the resulting metabolite to determine the safety of the compound. According to this method, it can be determined whether a test compound will be converted into a carcinogenic or mutagenic form through the metabolism in the human liver, and whether the test compound or its metabolite has mutagenicity.
