Cytochrome c3 family protein
WebCytochrome c 3 can serve as a uranium reductase and involved in the shuttling of electron to U(VI) (Payne et al., 2002). The gene responsible for U(VI) reduction by D. desulfuricans has been identified as cycA. CycA gene consists of 461-bp nucleotide sequence and encodes a tetraheme cytochrome c 3 protein of 130 amino acids and molecular mass ...

WebSep 1, 2024 · Abstract. Cytochrome c, a protein that belongs to class 1 of the c-type cytochrome family, exerts different functions depending on its cellular localization and the conditions in which it operates; therefore, it can be defined as 'extreme multifunctional' protein. It mediates electron-transfer in the respiratory chain and acts as a detoxifying ...
WebCytochrome c3 isolated from a sulfate-reducing bacterium, Desulfovibrio vulgaris Miyazaki F, is a tetraheme protein. Its physiological partner, [NiFe] hydrogenase, catalyzes the reversible oxidoreduction of molecular hydrogen. To elucidate the mechanism of electron transfer between cytochrome c3 and [NiFe] hydrogenase, the transient complex ...
Cytochrome c proteins can be divided in four classes based on their size, number of heme groups and reduction potentials: 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 ligand provided by a methionine re… WebJun 24, 2024 · The cytochrome c 6 family of proteins plays an essential role in photosynthetic electron transfer, but the evolutionary relationships among the members of the family remain unclear.
