Protein

Cytochrome P450 2A3

Gene

Cyp2a3

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

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 unrelated compounds, including steroids, fatty acids, and xenobiotics.

Catalytic activityi

RH + reduced flavoprotein + O2 = ROH + oxidized flavoprotein + H2O.
