Biochemistry of arsenic detoxification
TLDR
While the overall schemes for arsenic resistance are similar in prokaryotes and eukaryotes, some of the specific proteins are the products of separate evolutionary pathways.About:

Occurrence of arsenic contamination in Canada: sources, behavior and distribution.
TL;DR: An analysis of the currently available information on recognized problem areas, and an overview of current knowledge of the principal hydrogeochemical processes of arsenic transportation and transformation are provided, however, a more detailed understanding of local sources of arsenic and mechanisms of arsenic release is required.

Asp45 Is a Mg2+ Ligand in the ArsA ATPase
Tongqing Zhou,Barry P. Rosen +1 more
TL;DR: Results indicate that Asp45 is a Mg2+-responsive residue, consistent with its function as a M g2+ ligand in ArsA, which is allosterically activated by arsenite or antimonite.
Journal ArticleDOI
The anion-stimulated atpase arsa shows unisite and multisite catalytic activity
TL;DR: It is demonstrated that the A1 domain is capable of carrying out unisite catalysis in the absence of antimonite, and the linker region, where ADP binds under both unisite and multisite catalytic conditions, may play an important role in the energy transduction process.
Journal ArticleDOI
Role of conserved histidine residues in metalloactivation of the ArsA ATPase.
TL;DR: Results suggest that the histidine residues play a role in transmission of the signal between the catalytic and allosteric sites to activate ATP hydrolysis.
