1 Evidence for the metabolism of N-nitrosodimethylamine and carbon tetrachloride by a common isozyme of cytochrome P-450. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
2 Carbon tetrachloride administration to rats produced a selective loss of hepatic cytochrome P-450-dependent catalytic activities. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
3 Of the cytochrome P-450-dependent catalytic activities tested, the metabolism of carbon tetrachloride to phosgene and the low Km N-nitrosodimethylamine demethylase were the most sensitive to destruction by carbon tetrachloride. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
4 Of the cytochrome P-450-dependent catalytic activities tested, the metabolism of carbon tetrachloride to phosgene and the low Km N-nitrosodimethylamine demethylase were the most sensitive to destruction by carbon tetrachloride. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
5 The similarities between both the loss and the induction of the low Km N-nitrosodimethylamine demethylase and the metabolism of carbon tetrachloride to phosgene suggest that these catalytic activities represent a common isozyme of cytochrome P-450. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
6 Analysis of cytochromes P-450 by HPLC provided evidence for an isozyme of cytochrome P-450 inducible by pyrazole and destroyed by carbon tetrachloride. Carbon Tetrachloride cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus
