C-type cytochromes
WebCytochrome c can be measured in human serum and can be used as a marker for inflammation. [7] In addition to these equatorial covalent bonds, the heme iron is also usually axially coordinated to the side chains of two amino acids, making the iron hexacoordinate. WebHeme is one of the most pervasive cofactors in nature and the c-type cytochromes represent one of the largest families of heme-containing proteins. Recent progress in bacterial genomic analysis has revealed a vast range of genes encoding novel c-type cytochromes that contain multiple numbers of heme cofactors. The

Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of Biochemistry and Molecular Biology (IUBMB), cytochromes a, cytochromes b, c… WebSpectral and electrochemical characterization of EOCs indicated the presence of flavins and c-type cytochromes (c-Cyts).

WebC -type cytochromes (CytC) are electron-transfer proteins that have one or more heme c groups. They are characterized by the covalent attachment of the heme to the polypeptide chain via two (or rarely one) thioether bonds formed between thiol groups of cysteine residues and vinyl groups of the heme molecule. Cytochrome c is a highly conserved protein across the spectrum of eukaryotic species, found in plants, animals, fungi, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of cladistics.
