Cytochrome C - an overview ScienceDirect Topics

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… 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. bishops lydeard fc twitter
