WebDec 26, 2003 · Here, we show that coexpression from plasmids of a variant of cytochrome b562 containing a CXXCH heme-binding motif with the E. coli cytochrome c maturation (Ccm) proteins results in an essentially homogeneous product that is a correctly matured c-type cytochrome. Formation of the holocytochrome was accompanied by substantial … WebNov 30, 1999 · The heme prosthetic group of cytochrome c is covalently attached to the protein through thioether bonds to two cysteine side chains. The role of covalent heme attachment to cytochrome c is not understood, and most heme proteins bind the prosthetic group by iron ion ligation and tertiary interactions only. A two-armed attachment seems …
