Cytochrome foie
WebSince its discovery in the 1980s, the fatty acid hydroxylase flavocytochrome P450 (cytochrome P450) BM3 (CYP102A1) from Bacillus megaterium has been adopted as a paradigm for the understanding of structure and mechanism in the P450 superfamily of enzymes. P450 BM3 was the first P450 discovered as a … WebThe absorption of cytochrome c at 550 nm changes with its oxidation state. This property is the basis for the assay.3 Cytochrome c is reduced with dithiothreitol and then reoxidized by the cytochrome c oxidase. The difference in extinction coefficients ( mM) between reduced and oxidized cytochrome c is 21.84 at 550 nm.9
