WebNov 8, 2024 · In all cytochrome P450s, the catalytic heme is anchored to the active site with a highly conserved thiolate ligand (FXXGXXXCXG) and splits molecular oxygen, with one oxygen molecule oxidizing the substrate while the other is reduced to water (Porter and Coon 1991; Bolwell et al. 1994 ). WebCytochromes P450 ( CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. [1] [2] [3] In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown.
