Possible Dynamically Gated Conductance along Heme Wires in Bacterial Multiheme Cytochromes

The Journal of Physical Chemistry B, 2014
The staggered cross decaheme configuration of electron transfer cofactors in the outer-membrane cytochrome MtrF serves as a prototype for conformationally gated multiheme electron transport. Derived from the bacterium Shewanella oneidensis, the staggered cross configuration reveals intersecting c-type octaheme and tetraheme "wires" containing ...

Heme Cluster Structures and Electron Transfer in Multiheme Cytochromes C3

1987
Cytochromes C3 (molecular weight around 14000) form a class of multiheme cytochromes which are present in all anaerobic sulfate-reducing bacteria belonging to the genus Desulfovibrio (1). They are essential electron carriers in several electron transfer processes and their oxidation-reduction properties have been studied in some detail (2).

Electron transfer between hydrogenases and mono- and multiheme cytochromes in Desulfovibrio ssp

JBIC Journal of Biological Inorganic Chemistry, 1998
A comparative study of electron transfer between the 16 heme high molecular mass cytochrome (Hmc) from Desulfovibrio vulgaris Hildenborough and the [Fe] and [NiFe] hydrogenases from the same organism was carried out, both in the presence and in the absence of catalytic amounts of cytochrome c3.

Molecular details of multielectron transfer: the case of multiheme cytochromes from metal respiring organisms

Dalton Trans., 2010
Shewanella are facultative anaerobic bacteria of remarkable respiratory versatility that includes the dissimilatory reduction of metal ores. They contain a large number of multiheme c-type cytochromes that play a significant role in various anaerobic respiratory processes.

Electrochemical and Spectroscopical Characterisation of the Multiheme Cytochrome Subunit of the Reaction Center of Chloroflexus Aurantiacus

1993
The photosynthetic reaction center (RC) of Cf. aurantiacus contains a multiheme cytochrome subunit which is responsible for the rereduction of the photooxidized primary electron donor. In contrast to the hemes of the cytochrome subunit of Rps.vihdis, all hemes exhibit the same α-band absorption at 554 nm, thus rendering an individual titration of their
