.... This serves to highlight several unanswered questions relating to the regulation of respiratory electron transport in Shewanella and the central role(s) of the tetrahaem-containing quinol dehydrogenase CymA in that process. cytochrome electrochemistry haem mineral reduction quinone Shewanella...

... transfer includes the decahaem cytochrome DmsE, a paralogue of the MtrA family of decahaem cytochromes. Although both DmsE and MtrA are decahaem cytochromes implicated in the long-range electron transfer across a ~300 Å (1 Å=0.1 nm) wide periplasmic ‘gap’, MtrA has been shown to be only 105 Å in maximal...

... membranes and separation by sucrose gradient centrifugation ( Figure 1 ). The experiments provide useful confirmation that AniA [and Laz (lipid-modified azurin), see below] are found in the outer membrane, whereas the c -type cytochromes are associated with the inner membrane. Figure 1 Localization...

... and mechanistic insights that may be afforded by working with such electrodes through studies of Escherichia coli NrfA, a pentahaem cytochrome with nitrite and nitric oxide reductase activities. In addition, we demonstrate that the ability to characterize electrocatalytically active protein films by MCD (magnetic...

...D. Pompon; A. Laisné Different semi-synthetic PDNAs (protein–DNA complexes), which encompass a protein core engineered from the cytochrome b 5 scaffold, an embedded tuneable redox cofactor, a synthetic linker and a large oligonucleotide, were designed, synthesized and purified to homogeneity...

...M. Deeudom; J. Rock; J. Moir The ability of Neisseria meningitidis to utilize both oxygen and nitrogen oxides as respiratory substrates allows it to thrive in the diverse environment of the human host. Genome analysis highlighted genes encoding a cbb 3 cytochrome oxidase, the aniA nitrite reductase...
