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:

Mechanisms of bacterial degradation of arsenic
TL;DR: Arsenic is a toxic metalloid that exists in two major forms (arsenate and arsenite). The anthropogenic activities of man are its major source in the environment as mentioned in this paper.

Arsenic speciation in Asiatic algae: Case studies in Asiatic continent
Lizhao Chen,Li Zhang +1 more
TL;DR: This chapter reviewed the As bioaccumulation and speciation in microalgae and macroalgae from Asiatic continent and illuminated the As biotransformation processes as well as their genes involved in algae.
Annotating adverse outcome pathways to organize toxicological information for risk assessment
TL;DR: A data model containing terms from 22 controlled vocabularies to annotate currently existing AOP’s and to inform future AOP development is presented, providing the ability to attach scientific evidence in support of the AOP, supports data aggregation, and promotes the development of AOP networks.
Dissertation
Development of a sustainable method for the disposal ofchromated copper arsenate (CCA) treated wood
TL;DR: In this paper, the authors investigated the possibility of producing ethanol from CCA wood and found that the presence of copper, chromium and arsenic did not have a negative effect on the fermentation process.

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.
