Haloarculaceae

	Haloarculaceae ''Haloarculaceae'' is a family of halophilic and mostly chemoorganotrophic archaea within the order ''Halobacteriales''. The type genus of this family is ''Haloarcula.'' Its biochemical characteristics are the same as the order ''Halobacteriales.'' The name ''Haloarculaceae'' is derived from the Latin term ''Haloarcula,'' referring to the type genus of the family and the suffix "-ceae," an ending used to denote a family. Together, ''Haloarculaceae'' refers to a family whose nomenclatural type is the genus ''Haloarcula.'' Current Taxonomy and Molecular Signatures As of 2021, ''Haloarculaceae'' contains 10 validly published genera. This family can be molecularly distinguished from other Halobacteria by the presence of 19 conserved signature proteins (CSPs) and seven conserved signature indels (CSIs) present in the following proteins: acetylglutamate kinase, ribonuclease R, metallo-beta-lactamase, tRNA modifying enzyme, carbamoyl phosphate synthase large subunit and hypothetical ...

	Halobacteria Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt. Halobacteria are now recognized as archaea rather than bacteria and are one of the largest groups. The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and while valid according to taxonomic rules, should be updated. Halophilic archaea are generally referred to as haloarchaea to distinguish them from halophilic bacteria. These microorganisms are among the halophile organisms, that they require high salt concentrations to grow, with most species requiring more than 2.0M NaCl for growth and survival. They are a distinct evolutionary branch of the Archaea distinguished by the possession of ether-linked lipids and the absence of murein in their cell walls. Haloarchaea can grow aerobically or anaerobically. Parts of the membranes of haloarchaea are purpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Halobacteriales In taxonomy, the Halobacteriales are an order of the Halobacteria, found in water saturated or nearly saturated with salt. They are also called halophiles, though this name is also used for other organisms which live in somewhat less concentrated salt water. They are common in most environments where large amounts of salt, moisture, and organic material are available. Large blooms appear reddish, from the pigment bacteriorhodopsin. This pigment is used to absorb light, which provides energy to create ATP. Halobacteria also possess a second pigment, halorhodopsin, which pumps in chloride ions in response to photons, creating a voltage gradient and assisting in the production of energy from light. The process is unrelated to other forms of photosynthesis involving electron transport; however, and halobacteria are incapable of fixing carbon from carbon dioxide. Halobacteria can exist in salty environments because although they are aerobes they have a separate and different way o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	List Of Archaea Genera This article lists the genera of the Archaea. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from the GTDB release 07-RS207 (8th April 2022). The position of clades with a "question mark" are based on the additional phylogeny of the 16S rRNA-based LTP_12_2021 by The All-Species Living Tree Project. Phylum " Altarcha ...

	Haloarcula ''Haloarcula'' (common abbreviation ''Har.'') is a genus of extreme halophilic Archaea in the class of Halobactaria. Cell Structure ''Haloarcula'' species can be distinguished from other genera in the family Halobacteriaceae by the presence of specific derivatives of TGD-2 polar lipids. ''H. quadrata'' has predominantly flat, square-shaped, somewhat pleomorphic cells. Metabolism ''H. quadrata'' was first isolated when researchers were attempting to culture ''Haloquadratum walsbyi'', a haloarchaeon that was thought to be unculturable until 2004. Similar to other halophilic archaea, ''Haloarcula'' species grow optimally at 40–45 °C. Growth appears in sheets of up to 65 cells often in the shape of a square or triangle. Taxonomy The genus of ''Haloarcula'' was long grouped with other halophilic archaea such as '' Halobacterium'' until genomic analysis prompted to reorder this genus in the new family of Haloarculaceae.

	Natronomonas ''Natronomonas'' (common abbreviation ''Nmn.''). is a genus of the Halobacteriaceae.See the NCBIbr>webpage on Natronomonas Data extracted from the Description and significance ''Natronomonas pharaonis'' is an aerobic, extremely haloalkaliphilic archaeon that grows optimally in 3.5M sodium chloride and at pH 8.5, but is sensitive to high magnesium concentrations. Genome structure The genome of ''Natronomonas pharaonis'' consists of three circular replicons, the chromosome which is 2,595,221 bp in length, a typical haloarchaeal 131-kb plasmid, and a unique multicopy 23-kb plasmid. Its chromosome has a high G + C content (63.4%). Also, a high proportion of acidic amino acids (average 19.3%) is found in the proteins of ''N. pharaonis'' which results in low isoelectric points (average pI 4.6). This is considered to be one of the adaptive features of haloarchaea, which are known to apply the salt-in strategy (high internal salt concentrations) in order to survive in their hype ...
