TL;DR: The knowledge of these proteins has expanded in the past decade, as a result of contributions at the biochemical level and the sequencing of the genomes from several organisms, which showed that most organisms contain genes that potentially encode NDH-2.

TL;DR: The current knowledge on the composition and properties of the aerobic and anaerobic pathways of dissimilatory elemental sulfur metabolism in thermophilic archaea is summarized in this contribution.

TL;DR: Oxygen consumption was measured in membrane fractions upon thiosulphate addition, thus linking thiosULphate oxidation to dioxygen reduction, in what constitutes a novel activity among Archaea.

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.

TL;DR: The first three-dimensional crystal structure of the human RuvBL complex with a truncated domain II is solved and it is shown that this complex is competent for helicase activity, suggesting that in vivo activities of these highly interesting therapeutic drug targets are regulated by cofactors inducing conformational changes via domain II in order to modulate the enzyme complex into its active state.
