Abstract

P450s are a superfamily of heme-containing monooxygenases and important in the metabolism of numerous physiological substrates and foreign compounds. It has been established that tilers are at least 30 distinct human isoforms of P450. Four families containing numerous individual P450s are mainly responsible for metabolizing foreign compounds, A cDNA expression system in which individual human P450s are synthesized in cultured human hepatoma (Hep G2) cells infected with a recombinant vaccinia virus containing human P450 cDNA has been constructed.
