The genome of Pelobacter carbinolicus reveals surprising metabolic capabilities and physiological features [PDF]

, 2012
Background The bacterium Pelobacter carbinolicus is able to grow by fermentation, syntrophic hydrogen/formate transfer, or electron transfer to sulfur from short-chain alcohols, hydrogen or formate; it does not oxidize acetate and is not known to ferment

Tethered heme domains in a triheme cytochrome allow for increased electron transport distances

Protein Science, Volume 33, Issue 11, November 2024.
Abstract Decades of research describe myriad redox enzymes that contain cofactors arranged in tightly packed chains facilitating rapid and controlled intra‐protein electron transfer. Many such enzymes participate in extracellular electron transfer (EET), a process which allows microorganisms to conserve energy in anoxic environments by exploiting ...

Metabolic versatility of aerobic methane‐oxidizing bacteria under anoxia in aquatic ecosystems

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
Besides conventional aerobic oxidation pathway, MOB has four underlying metabolic strategies under anoxia: (i) forming a consortium with oxygenic microorganisms; (ii) self‐generation/storage of O2 by MOB; (iii) forming a consortium with non‐oxygenic heterotrophic bacteria that use other electron acceptors; (iv) and utilizing alternative electron ...

Electron Accepting Units of the Diheme Cytochrome c TsdA, a Bifunctional Thiosulfate Dehydrogenase/Tetrathionate Reductase [PDF]

, 2016
The enzymes of the thiosulfate dehydrogenase (TsdA) family are wide-spread diheme c-type cytochromes. Here, redox carriers were studied mediating the flow of electrons arising from thiosulfate oxidation into respiratory or photosynthetic electron chains.
