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

open access: yesChemElectroChem, 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.

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

open access: yes, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

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

open access: yesPLoS 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 ...

Import of cytochrome c into mitochondria. Cytochrome c heme lyase [PDF]

open access: yesEuropean Journal of Biochemistry, 1987
The import of cytochrome c into mitochondria can be resolved into a number of discrete steps. Here we report on the covalent attachment of heme to apocytochrome c by the enzyme cytochrome c heme lyase in mitochondria from Neurospora crassa. A new method was developed to measure directly the linkage of heme to apocytochrome c. This method is independent

H NMR Studies of Eukaryotic Cytochrome c [PDF]

open access: yes, 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 ...

Importance of c-Type cytochromes for U(VI) reduction by Geobacter sulfurreducens

open access: yesBMC Microbiology, 2007
Background In order to study the mechanism of U(VI) reduction, the effect of deleting c-type cytochrome genes on the capacity of Geobacter sulfurreducens to reduce U(VI) with acetate serving as the electron donor was investigated.

Unique organizational and functional features of the cytochrome c maturation system in Shewanella oneidensis. [PDF]

open access: yesPLoS ONE, 2013
Shewanella are renowned for their ability to respire on a wide range of electron acceptors, which has been partially accredited to the presence of a large number of the c-type cytochromes. In the model species S. oneidensis MR-1, at least 41 genes encode

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

open access: yes, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

Isolation and Polyphasic Characterization of Desulfuromonas versatilis sp. Nov., an Electrogenic Bacteria Capable of Versatile Metabolism Isolated from a Graphene Oxide-Reducing Enrichment Culture

open access: yesMicroorganisms, 2021
In this study, a novel electrogenic bacterium denoted as strain NIT-T3 of the genus Desulfuromonas was isolated from a graphene-oxide-reducing enrichment culture that was originally obtained from a mixture of seawater and coastal sand.
