Abstract
The marine fish Mugil cephalus was caught in the Bay of Marseilles (France) in 1985 and the liver microsomal cytochrome P450 was identified at a concentration of about 0.230 nmol mg-1 protein. Optimal assay conditions were established to measure two mixed-function cytochrome P450-dependent oxidases: aniline hydroxylase and p-nitroanisole O-demethylase. Induction of cytochrome P450 occurred after exposure of mullet to an aromatic hydrocarbon and a water-soluble petroleum fraction. The liver cytochrome P450 was solubilized and purified. The monomer molecular weight of partially purified cytochrome P450, determined by sodium dodecyl-sulfate-gel electrophoresis, was 51 000.
