WebJan 1, 2024 · The cytochromes P450 (P450s or CYPs) form a superfamily of enzymes found in organisms from archaea and bacteria through to man (Munro et al. 2007 ). P450s were discovered as a consequence of their unusual UV-visible absorbance properties, originating from their heme cofactor, which is bound to the protein through a cysteine sulfur in its ... WebCytochrome P450. Cytochromes 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. list spn for an account
