Genome-enabled studies of anaerobic, nitrate-dependent iron oxidation in the chemolithoautotrophic bacterium Thiobacillus denitrificans

Frontiers in Microbiology, 2013
Thiobacillus denitrificans is a chemolithoautotrophic bacterium capable of anaerobic, nitrate-dependent U(IV) and Fe(II) oxidation, both of which can strongly influence the long-term efficacy of in situ reductive immobilization of uranium in contaminated

Cytochromes c550, c552, c1 in the electron transport network of Paracoccus denitrificans: redundant or subtly different in function? [PDF]

, 2001
Paracoccus denitrificans strains with mutations in the genes encoding the cytochrome c550, c552, or c1 and in combinations of these genes were constructed, and their growth characteristics were determined.

Maturation of Plastid c-type Cytochromes

Frontiers in Plant Science, 2017
Cytochromes c are hemoproteins, with the prosthetic group covalently linked to the apoprotein, which function as electron carriers. A class of cytochromes c is defined by a CXXCH heme-binding motif where the cysteines form thioether bonds with the vinyl ...

Different outer membrane c‐type cytochromes are involved in direct interspecies electron transfer to Geobacter or Methanosarcina species

mLife, 2022
Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor.

Reduction Kinetic of Water Soluble Metal Salts by Geobacter sulfurreducens: Fe2+/Hemes Stabilize and Regulate Electron Flux Rates

Frontiers in Microbiology, 2022
Geobacter sulfurreducens is a widely applied microorganism for the reduction of toxic metal salts, as an electron source for bioelectrochemical devices, and as a reagent for the synthesis of nanoparticles.

A dedicated haem lyase is required for the maturation of a novel bacterial cytochrome c with unconventional covalent haem binding [PDF]

, 2007
In bacterial c-type cytochromes, the haem cofactor is covalently attached via two cysteine residues organized in a haem c-binding motif. Here, a novel octa-haem c protein, MccA, is described that contains only seven conventional haem c-binding motifs ...

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...

Electrochemical Characterization of the Periplasmic PpcA c‐Cytochrome of Geobacter sulfurreducens Reveals Its Affinity for Uranium

ChemElectroChem, 2023
Geobacter bacteria produce conductive pili appendages and an outer membrane‐anchored lipopolysaccharide to immobilize uranium extracellularly. Yet, some radionuclide enters the cell envelope, where is rapidly mineralized by periplasmic c‐cytochromes.

H NMR Studies of Eukaryotic Cytochrome c [PDF]

, 1982
H NMR resonance assignments in the spectra of horse, tuna, Neurmpora crassa and Candida krusei cyto-chromes c are described. Assignments have been made using NMR double-resonance techniques in conjunction with electron-exchange experiments, spectral ...

Real-time measurements of the redox states of c-type cytochromes in electroactive biofilms: a confocal resonance Raman Microscopy study.

PLoS ONE, 2014
Confocal Resonance Raman Microscopy (CRRM) was used to probe variations of redox state of c-type cytochromes embedded in living mixed-culture electroactive biofilms exposed to different electrode polarizations, under potentiostatic and potentiodynamic ...
