Protein
Cytochrome P450 1A1
Gene
cyp1a1
Organism
Oncorhynchus mykiss (Rainbow trout) (Salmo gairdneri)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Cytochromes P450 are a group of heme-thiolate monooxygenases. They oxidize a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.

Catalytic activityi

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

Cofactori

Heme group By similarity.

    Sequence cautioni

    The sequence AAA49550.1 differs from that shown. Reason: Chimera. Its N-terminal part has been shown to be derived from what is now known as the CYP1A3. CYP1A1 has also been called CYP1A2.
