Cytochrome P450 1A2

Gene

CYP1A2

Organism
Cavia porcellus (Guinea pig)
Status
Reviewed-Annotation score: Annotation score: 3 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. Most active in catalyzing 2-hydroxylation.By similarity

Catalytic activityi

RH + [reduced NADPH--hemoprotein reductase] + O2 = ROH + [oxidized NADPH--hemoprotein reductase] + H2O.By similarity
