Protein
Cytochrome P450 2C18
Gene
CYP2C18
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein 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.

Cofactori

Heme group By similarity.
