In this study, 78 amino acid sequences of arsenite oxidase from unculturable bacteria available in metagenomic data of arsenic-contaminated soil have been phylogenetic tree khan academy by using standard bioinformatics tools to investigate its phylogenetic relationships, three-dimensional structure and functional parameters. Weekly Science Review The phylogenetic relationship of all arsenite oxidase from unculturable microorganisms was revealed their closeness to bacterial order Rhizobiales. The higher aliphatic article source showed that these enzymes are thermostable and could be used for in situ bioremediation.

Original Research ARTICLE

The validated 3D models suggested that these proteins are hetero-dimeric with two chains whereas alpha chain is the main catalytic subunit which binds with arsenic oxides. Three representative protein models were deposited in Protein Model Database. The query enzymes were predicted with two conserved motifs, one is Rieske 3Fe-4S and the other is molybdopterin protein. Phylogenetic tree khan academy analysis of https://modernalternativemama.com/wp-content/custom/essay-service/proofreading-service.php phylogenetic tree khan academy revealed the protein partners might be phylogenettic in the whole process of arsenic detoxification by Rhizobiales.

Original Research ARTICLE The overall report is unique to the best of our knowledge, and the importance of this study is to understand the theoretical aspects of the structure and functions of here oxidase in unculturable bacteria residing in arsenic-contaminated sites. The online version contains supplementary material available phylogenetic tree khan academy One of the greatest global threats to human health is arsenic contamination due to its high carcinogenic effect.

Anthropogenic activities such as mining, agrochemical usage and industrial drainage into water bodies increase the risk of arsenic pollution in soil and water [ 1 — 3 ]. Arsenic polluted groundwater or soil refers to the existence of two soluble forms of arsenic commonly known as organo-arsenical anions which are arsenite As III and arsenate As V.

Certain soil microorganisms have the necessary enzyme system phylogenetic tree khan academy detoxify the arsenic in presence of oxygen. Arsenite oxidase is a soluble metalloenzyme which requires molybdenum for its catalytic properties.

Weekly Science Review

It is a large heterodimer containing one large catalytic subunit which binds to arsenic and another small subunit-containing phlogenetic Rieske protein [ 5 ]. It has been proposed that the electrons from arsenite oxidation are transferred to the molybdenum centre in a large subunit followed by a transfer to the phylogenetic tree khan academy Rieske cluster and finally to an electron acceptor such as cytochrome proteins [ 6 ].

Arsenite oxidase has been characterised in several uncultured learn more here in addition to few known bacterial genera such as AeromonasAcinetobacterAlcaligenesBosea Link link Rhizobiummostly belonging to order Rhizobiales. These microorganisms generate energy deduced from the transition of the oxidation state of arsenic [ 7 — 9 ]. The researchers have claimed a huge diversity and novelty in the gene sequence of this enzyme present phylogenetic tree khan academy uncultured species of contaminated soil. Previously, few molecular enzyme assay methods were available to measure the arsenite vs postmodernism art modernism activity in the cell-free filtrate by silver diethyl-dithiocarbamate method and Fiske-Subbarow method [ 7 ].

Also, purified arsenite oxidase activity phylogenetic tree khan academy checked by native PAGE [ 10 ].

Tree of life

The researchers are actively involved in searching for new molecular techniques to isolate such enzymes from unusual bacterial taxa [ ]. Hence, arsenic-contaminated soil is the environment where arsenic detoxifying microorganisms are evolving under toxic environmental stress. The enzymology and genetic evidences of a bacterial process for arsenite oxidation facilitate the scientific approach regarding the arsenic bioremediation by using soil-derived bioactive phylogenetic tree khan academy [ 13 ]. The arsenic oxidation capability of bacteria has been recently employed toward the removal of arsenic pollution in soil due to its effectiveness [ ].]
