MeSH definition : A liver microsomal cytochrome P-450 monooxygenase capable of biotransforming xenobiotics
such as polycyclic hydrocarbons and halogenated aromatic hydrocarbons into carcinogenic
or mutagenic compounds. They have been found in mammals and fish. This enzyme, encoded
by CYP1A1 gene, can be measured by using ethoxyresorufin as a substrate for the ethoxyresorufin
O-deethylase activity.;
