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. WebCytochrome c oxidase, a membrane-bound enzyme in the respiratory chain of aerobic organisms, reduces oxygen to water. This process which takes place at the binuclear metal centre constituted by a haem a3 and a Cu ion runs via several intermediate states with life times in the micro- and millisecond range. WebMetal centers from enzyme proteins may give essential data for the design of biomimetic enzymes in bioorganic synthesis. Biomimetic metal centers from enzymes such as cytochrome oxidases (with Fe-porphyrin), catechol oxidase (based on Mn(IV)-complexes with o-aminophenol ligands), or hydrogenase (based, e.g., on six-coordinate Ni-Ru … drawing hard pictures
