Cytochrome c heme attachment protein
WebCytochrome c 1 is a 30 kDa protein. It is anchored to the mitochondrial inner membrane by a transmem-brane helix with its soluble domain (and heme) in the IMS (Fig. 3). It transfers electrons from the Rieske iron-sulfur protein of the bc 1 complex to cyto-chrome c [6]. Heme attachment to c-type cytochromes is a cataly-sed post-translational ... WebHeme prosthetic group of cytochrome c, consisting of a rigid porphyrin ring coordinated with an iron atom. The cytochrome complex, or cyt c, is a small hemeprotein found loosely associated with the inner membrane of …

WebJul 3, 2024 · The covalent attachment of one or multiple heme cofactors to cytochrome c protein chains enables cytochrome c proteins to be used in electron transfer and redox catalysis in extracytoplasmic environments.
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. WebSep 6, 2011 · A heme-binding role for HCCS might be expected as heme is one of the two substrates. Such binding has been suggested in a study indicating heme binding to a CPV motif in Saccharomyces cerevisiae HCC 1 S , the protein required for heme attachment to cytochrome c 1 in fungi. CP sequences have been described as heme-regulatory motifs …
WebEfficient nanomaterials for artificial photosynthesis require fast and robust unidirectional electron transfer (ET) from photosensitizers through charge-separation and accumulation … WebCytochrome c, shown here from PDB entry 3cyt , is a carrier of electrons. Like many proteins that carry electrons, it contains a special prosthetic group that handles the slippery electrons. Cytochrome c contains a heme group with an iron ion gripped tightly inside, colored red here. The iron ion readily accepts and releases an electron.
