... biological strategy of electron hopping/tunnelling between closely spaced redox-active proteins. The multihaem c -type cytochrome OmcS is specifically associated with pili and is necessary for Fe(III) oxide reduction. However, multiple lines of evidence, including the metallic-like conductivity of the pili...

.... The protein components identified to date for the Mtr pathway of MR-1 include four multihaem c -Cyts ( c -type cytochromes), CymA, MtrA, MtrC and OmcA, and a porin-like outer membrane protein MtrB. They are strategically positioned along the width of the MR-1 cell envelope to mediate electron transfer from...

... of MamE, MamP and MamT. Initial biophysical characterization has confirmed that MamE, MamP and MamT are indeed c -type cytochromes. Furthermore, determination of redox potentials for this new family of c -type cytochromes reveals midpoint potentials of −76 and −32 mV for MamP and MamE respectively...

...J.W.A. Allen; S.J. Ferguson c -Type cytochromes are characterized by covalent attachment of haem to protein through thioether bonds between the vinyl groups of the haem and the thiols of a Cys-Xaa-Xaa-Cys-His motif. Proteins of this type play crucial roles in the biochemistry of the nitrogen cycle...

...J.W.A. Allen; M.L. Ginger; S.J. Ferguson c -type cytochromes contain haem covalently attached to protein by thioether bonds formed post-translationally and requiring a dedicated biogenesis apparatus. Three biogenesis systems, found in different cell types, are well known. Here we discuss emerging...
