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 ...

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.

Cloning, sequencing, and characterization of the hexahydro-1,3,5-trinitro-1,3,5-triazine degradation gene cluster from Rhodococcus rhodochrous [PDF]

open access: yes, 2002
Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a high explosive which presents an environmental hazard as a major land and groundwater contaminant.

Cytochrome c binding affects the conformation of cytochrome a in cytochrome c oxidase.

open access: yesJournal of Biological Chemistry, 1992
Second derivative absorption spectroscopy has been used to assess the effects of complex formation between cytochrome c and cytochrome c oxidase on the conformation of the cytochrome a cofactor. When ferrocytochrome c is complexed to the cyanide-inhibited reduced or mixed valence enzyme, the conformation of ferrocytochrome a is affected.

The Small RNA RyhB Is a Regulator of Cytochrome Expression in Shewanella oneidensis

open access: yesFrontiers in Microbiology, 2018
Shewanella oneidensis produces an extensive electron transfer network that results in metabolic flexibility. A large number of c-type cytochromes are expressed by S.
