The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]
Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of

The Carbon Monoxide Dehydrogenase from Desulfovibrio vulgaris
Ni-containing Carbon Monoxide Dehydrogenases (CODHs) catalyze the reversible conversion between CO and CO₂and are involved in energy conservation and carbon fixation. These homodimeric enzymes house two NiFeS active sites (C-clusters) and three accessory [4Fe-4S] clusters.

Antibiotic-Resistant Desulfovibrio Produces H2S from Supplements for Animal Farming
Sulphate-reducing bacteria, primarily Desulfovibrio, are responsible for the active generation of H2S in swine production waste. The model species for sulphate reduction studies, Desulfovibrio vulgaris strain L2, was previously isolated from swine manure

Selection for novel, acid-tolerant Desulfovibrio spp. from a closed Transbaikal mine site in a temporal pH- gradient bioreactor [PDF]
Almost all the known isolates of acidophilic or acid-tolerant sulphate-reducing bacteria (SRB) belong to the spore-forming genus Desulfosporosinus in the Firmicutes.

A functional description of CymA, an electron-transfer hub supporting anaerobic respiratory flexibility in Shewanella [PDF]
CymA (tetrahaem cytochrome c) is a member of the NapC/NirT family of quinol dehydrogenases. Essential for the anaerobic respiratory flexibility of shewanellae, CymA transfers electrons from menaquinol to various dedicated systems for the reduction of ...

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Characterization of a trithionate reductase system from Desulfovibrio vulgaris [PDF]
A trithionate reductase system was isolated and purified from extracts of Desulfovibrio vulgaris. This system reduced trithionate to thiosulfate and consisted of two proteins. One was bisulfite reductase, an enzyme that reduces bisulfite to trithionate, and the second component was designated TR-1.

Integrated structural analysis of N. vulgaris formate dehydrogenase AB, an enzyme with applications in climate change mitigation, is reported. The substrate/product diffusion pathways were fully mapped, and a retention site was identified that transiently holds substrates and has a key role in CO2‐reducing activity.

Homology modeling of the spatial structure of HydSL hydrogenase from purple sulphur bacterium Thiocapsa roseopersicina BBS [PDF]
The results of homology modeling of HydSL, a NiFe-hydrogenase from purple sulphur bacterium Thiocapsa roseopersicina BBS are presented in this work. It is shown that the models have larger confidence level than earlier published ones; a full-size model ...

Structural Insights into Dissimilatory Sulfite Reductases: Structure of Desulforubidin from Desulfomicrobium Norvegicum [PDF]
Dissimilatory sulfite reductases (dSiRs) are crucial enzymes in bacterial sulfur-based energy metabolism, which is likely to have been present in some of the earliest life forms on Earth.
