Unique ID: D019363
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D019363
Annotation: do not confuse with other cytochrome P-450 CYP's
Scope Note: 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.
