Cytochrome P450 2E1

Gene

CYP2E1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Metabolizes several precarcinogens, drugs, and solvents to reactive metabolites. Inactivates a number of drugs and xenobiotics and also bioactivates many xenobiotic substrates to their hepatotoxic or carcinogenic forms.

Catalytic activityi

4-nitrophenol + NADPH + O2 = 4-nitrocatechol + NADP+ + H2O.1 Publication
