TL;DR: The crystal structure of the aldehyde oxido-reductase (Mop) from the sulfate reducing anaerobic Gram-negative bacterium Desulfovibrio gigas has been determined at 2.25 Å resolution by multiple isomorphous replacement and refined.

TL;DR: The crystal structure of the xanthine oxidase-related molybdenum-iron protein aldehyde oxido-reductase from the sulfate reducing anaerobic Gram-negative bacterium Desulfovibrio gigas (Mop) was analyzed in its desulfo-, sulfo-, oxidized, reduced, and alcohol-bound forms at 1.8-A resolution as mentioned in this paper.

TL;DR: The results show that DsrC is involved in sulfite reduction, which changes the mechanism of sulfate respiration, which has important implications for models used to date ancient sulfur metabolism based on sulfur isotope fractionations.

TL;DR: The first structure of a cytochrome from this family, NrfH from Desulfovibrio vulgaris, which forms a stable complex with its electron partner, the cy tochrome c nitrite reductase NrfA, is described.

TL;DR: A sulfide:quinone oxidoreductase (SQR) was isolated from the membranes of the hyperthermoacidophilic archaeon Acidianus ambivalens, and its X-ray structure revealed the presence of a chain of three sulfur atoms bridging those two cysteine residues.
