Curator comments
This enzyme listing is based on pharmacokinetic data for methylxanthines as a drug class. Methylxanthines are metabolized by CYP1A2. This drug is a methylxanthine and is therefore assumed to be metabolized by this enzyme.
General Function
Oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen
Specific Function
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally un...
