Protein

Cytochrome P450 2A11

Gene

CYP2A11

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the oxygenation of a variety of substrates, including ethanol and procarcinogens such as N-nitrosodiethylamine and phenacetin. Has no or little activity as a coumarin 7-hydroxylase and in the formation of androstenedione from testosterone.

Catalytic activityi

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