آرکی های اکستریم هالوفیل ، گروه متنوعی از پروکاریوتها می باشند که به خوبی با شرایط سخت هایپرسالین مانند غلظت های بالای نمک، خشکی شدید، دما و ph بالا سازگار شده اند. هم چنین دارای عمر بسیار طولانی اند که نتیجه پاکسازی سلول هایشان از استرس اکسیداتیو می باشد. علاوه بر این شباهت های کلیدی آنها به یوکاریوت ها ، آن ها را مدل های مناسب و ساده تری برای مطالعه مسیر های مولکولی(ترمیم dna و بیان ژن)، در ی...
The genus Haloarcula belongs to the family Halobacteriaceae which currently has 10 valid species. Here we report the draft genome sequence of strain SL3, a new species within this genus, isolated from the Solar Salterns of Cabo Rojo, Puerto Rico. Genome assembly performed using NGEN Assembler resulted in 18 contigs (N50 = 601,911 bp), the largest of which contains 1,023,775 bp. The genome consi...
BACKGROUND Goa is a coastal state in India and salt making is being practiced for many years. This investigation aimed in determining the culturable haloarchaeal diversity during two different phases of salt production in a natural solar saltern of Ribandar, Goa. Water and sediment samples were collected from the saltern during pre-salt harvesting phase and salt harvesting phase. Salinity and p...
During the search for haloarchaeal viruses, we isolated and characterized a new pleomorphic lipid-containing virus, Haloarcula hispanica pleomorphic virus 1 (HHPV-1), that infects the halophilic archaeon Haloarcula hispanica. The virus contains a circular double-stranded DNA genome of 8,082 bp in size. The organization of the genome shows remarkable synteny and amino acid sequence similarity to...
Yeast KEX2 protease was examined as a potential model for a human proprotein convertase and, in all respects, mimicked the predicted properties of a proalbumin convertase. The enzyme rapidly cleaved the propeptide Arg-Gly-Val-Phe-Arg-Arg from the NH2-terminal end of proalbumin but, unlike trypsin, failed to cleave physiologically unprocessed human proalbumin variants. There was little or no cle...
The carotenoids produced by extremely halophilic archaeon Haloarcula japonica were extracted and identified by their chemical, chromatographic, and spectroscopic characteristics (UV-Vis and mass spectrometry). The composition (mol%) was 68.1% bacterioruberin, 22.5% monoanhydrobacterioruberin, 9.3% bisanhydrobacterioruberin, <0.1% isopentenyldehydrorhodopin, and trace amounts of lycopene and phy...
