ATPase ASNA1

	ATPase ASNA1 ATPase ASNA1 also known as arsenical pump-driving ATPase and arsenite-stimulated ATPase is an enzyme that in humans is encoded by the ASNA1 gene. Function ASNA1 is the human homolog of the bacterial arsA gene. In ''E. coli'', arsA ATPase is the catalytic component of a multisubunit oxyanion pump that is responsible for resistance to arsenicals and antimonials. Interactions ASNA1 is found to interact with FAM71D according to STRING String or strings may refer to: String (structure), a long flexible structure made from threads twisted together, which is used to tie, bind, or hang other objects Arts, entertainment, and media Films ''Strings'' (1991 film), a Canadian anim ...

picture info	Enzyme An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

picture info	Gene In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Catalytic Catalysis () is the increase in reaction rate, rate of a chemical reaction due to an added substance known as a catalyst (). Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form reaction intermediate, intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst. The rate increase occurs because the catalyst allows the reaction to occur by an alternative mechanism which may be much faster than the noncatalyzed mechanism. However the noncatalyzed mechanism does remain possible, so that the total rate (catalyzed plus noncatalyzed) can only increase in the presence of the catalyst and never decrease. Catalysis may be classified as either homogeneous catalysis, homogeneou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Oxyanion An oxyanion, or oxoanion, is an ion with the generic formula (where A represents a chemical element and O represents an oxygen atom). Oxyanions are formed by a large majority of the chemical elements. The formulae of simple oxyanions are determined by the octet rule. The corresponding oxyacid of an oxyanion is the compound . The structures of condensed oxyanions can be rationalized in terms of AO''n'' polyhedral units with sharing of corners or edges between polyhedra. The oxyanions (specifically, phosphate and polyphosphate esters) adenosine monophosphate ( AMP), adenosine diphosphate ( ADP) and adenosine triphosphate (ATP) are important in biology. Monomeric oxyanions The formula of monomeric oxyanions, , is dictated by the oxidation state of the element A and its position in the periodic table. Elements of the first row are limited to a maximum coordination number of 4. However, none of the first row elements has a monomeric oxyanion with that coordination number. Instead, c ...

	Arsenical Arsenicals are chemical compounds that contain arsenic. In a military context, the term arsenical refers to toxic arsenic compounds that are used as chemical warfare agents. This includes blister agents, blood agents and vomiting agents. Historically, they were used extensively as Insecticide, insecticides, especially Lead hydrogen arsenate, lead arsenate. Examples Blister agents Ethyldichloroarsine Lewisite Methyldichloroarsine Phenyldichloroarsine Blood agents Arsine Vomiting agents Adamsite Diphenylchlorarsine Diphenylcyanoarsine Phenyldichloroarsine References Arsenic compounds Chemical weapons Poisons {{Chem-compound-stub ...

	Antimonial Antimonials, in pre-modern medicine, were remedies principally containing antimony, used chiefly for emetic purposes. They might also have qualified for cathartic, diaphoretic Perspiration, also known as sweat, is the fluid secreted by sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and Apocrine sweat gland, apocrine glands. The eccrine sweat glands are distribu ..., or simply alternative uses. Such treatments were considered unparalleled in their strength.

	FAM71D FAM71D, also known as chromosome 14 open reading frame 54 (C14orf54), is a protein that in humans is encoded by the FAM71D gene on Chromosome 7 (human), Chromosome 14. Homology (biology)#Orthology, Orthologs of FAM71D reach as far back in evolution to Reptiles, however, it is closer in homology to primates than any other orthologs. FAM71D has 6 paralogs: FAM71A, FAM71B, FAM71C, FAM71E1, FAM71F1, and FAM71F2 which encode a protein of unknown function. Gene In humans, FAM71D is located at 14q23.3 and stretches between positions 67189393 and 67228550 (span 39157 bp). It codes for at least 10 unique human protein isoforms: the primary isoform (422 aa; also denoted X1), isoform X2 (417 aa), isoform X3 (413 aa), isoform X4 (400 aa), isoform X5 (399 aa), isoform X6 (398 aa), isoform X7 (392 aa), isoform X8 (389 aa), isoform X9 (347 aa), isoform X10 (336 aa) In humans, FAM71D codes for an mRNA strand that is 1790 base pairs long.
