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:

Responses of earthworm Metaphire vulgaris gut microbiota to arsenic and nanoplastics contamination
Hong-Tao Wang,Lei Ma,Dong Zhu,Jing Ding,Gang Li,Bing-Jie Jin,Yuanhu Shao,Weixin Zhang,Meng-Ya Song,Shenglei Fu +9 more
TL;DR: In this paper, a microcosm study was performed to explore the effects of nanoplastics and arsenic on the microbiota characteristics in earthworm Metaphire vulgaris gut using Illumina high throughput sequencing, and to investigate changes in the gut microbiota-mediated arsenic biotransformation genes (ABGs) by using high-throughput quantitative PCR.

Redox biotransformation of arsenic along with plant growth promotion by multi-metal resistance Pseudomonas sp. MX6.
TL;DR: Multi-metal-resistant bacteria were isolated from a wastewater treatment plant showing resistance against As(III), As(V), Cr, Co, Cu, Cd, Hg, Ni, Pb, Se and Zn, which can be used as biofertilizers to reclaim the polluted lands and to enhance crop production in metal-contaminated soils.

Targeting microbial arsenic resistance genes: a new bioinformatic toolkit informs arsenic ecology and evolution in soil genomes and metagenomes
TL;DR: It was found that arsenic resistance genes were common, though not universally detected, in genomes and metagenomes from soils, contradicting the common conjecture that all organisms have arsenic resistanceGenetic diversity was examined, providing a synthesis of arsenic resistance from the most microbially diverse and complex environment.
A Harsh Life to Indigenous Proteobacteria at the Andean Mountains: Microbial Diversity and Resistance Mechanisms Towards Extreme Conditions
TL;DR: In this paper, Albarracin et al. present a paper on the use of microbiologists in the process of industrial processes in the context of the Argentina National Council of Investigaciones Cientificas and Tecnicas.
Dissertation
Bioremediation of arsenic contaminated groundwater.
TL;DR: In this paper, the authors used molasses as a possible source of carbon for the growth of sulphate-reducing bacteria (SRB) and investigated its chemical composition and the tolerance of SRB toward different arsenic species [As (III) and As (V)].

Distantly related sequences in the alpha- and beta-subunits of ATP synthase, myosin, kinases and other ATP-requiring enzymes and a common nucleotide binding fold.
TL;DR: Related sequences in both alpha and beta and in other enzymes that bind ATP or ADP in catalysis help to identify regions contributing to an adenine nucleotide binding fold in both ATP synthase subunits.

CLUSTAL: A package for performing multiple sequence alignment on a microcomputer
Desmond G. Higgins,Paul M. Sharp +1 more
TL;DR: An approach for performing multiple alignments of large numbers of amino acid or nucleotide sequences is described, based on first deriving a phylogenetic tree from a matrix of all pairwise sequence similarity scores obtained using a fast pairwise alignment algorithm.
Journal ArticleDOI
Classification and evolution of P-loop GTPases and related ATPases.
TL;DR: In this article, the authors compared sequences and available structures for all the widely distributed representatives of the P-loop GTPases and GTPase-related proteins with the aim of constructing an evolutionary classification for this superclass of proteins and reconstructing the principal events in their evolution.

Comparative toxicity of trivalent and pentavalent inorganic and methylated arsenicals in rat and human cells.
Miroslav Styblo,L.M. Del Razo,Libia Vega,Dori R. Germolec,Edward L. LeCluyse,G. Hamilton,W Reed,Changqing Wang,William R. Cullen,David J. Thomas +9 more
TL;DR: It is suggested that trivalent methylated arsenicals, intermediary products of arsenic methylation, may significantly contribute to the adverse effects associated with exposure to iAs, and high methylation capacity does not protect cells from the acute toxicity of triavalent arsenicals.

The MRP gene encodes an ATP-dependent export pump for leukotriene C4 and structurally related conjugates.
Inka Leier,Gabriele Jedlitschky,Ulrike Buchholz,Susan P.C. Cole,Roger G. Deeley,Dietrich Keppler +5 more
TL;DR: It is concluded that the biosynthetic release of LTC4 from cells is mediated by the 190-kDa product of the MRP gene, a primary-active ATP-dependent export pump for conjugates of lipophilic compounds with glutathione and several other anionic residues.
