Cytochrom c2

Cytochromes other than Cyt c 2 are synthesized by purple bacteria in different metabolic phases: isocytochrome c 2 and cytochrome c y (the latter membrane-bound) are present preferably in the presence of O 2, while Cyt c 2 transcription is increased in anoxic conditions, thus revealing that Cyt c 2 is mainly involved in photosynthesis, while iCyt c 2 and Cyt c y are involved in respiratory pathways Cytochrome c 2 is a single-heme soluble periplasm-located protein and acts as an electron deliverer. It accepts electrons from the Cyt c 1 of the bc 1 complex and is present both in the photosynthetic process and in respiration: respectively, it reduces the P + dimer to P, which is thus able to start a new photosynthetic turn, or reduces the cytochrome cbb 3 oxidase and in some organisms. Cytochrom c ist ein kleines Protein aus der Familie der Cytochrome, das in den Mitochondrien bei der oxidativen Phosphorylierung eine entscheidende Rolle als Elektronencarrier spielt. Orthologe des Cytochrom c kommen in allen Lebewesen als Mono- und Multimere vor. Beim Menschen sind Mutationen im CYCS-Gen mögliche Ursache für Cytochrom c-Mangel und familiäre Thrombozytopenie Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain (By similarity). By similarit Cytochrome c proteins can be divided in four classes based on their size, number of heme groups and reduction potentials:. Class I. Small soluble cytochrome c proteins with a molecular weight of 8-12 kDa and a single heme group belong to class I. It includes the low-spin soluble cytC of mitochondria and bacteria, with the heme-attachment site located towards the N-terminus, and the sixth.
