MicrobiologyOpen, Volume 8, Issue 9, September 2019., 2019 Cyclic di‐adenylate monophosphate (c‐di‐AMP) is an essential second messenger in bacteria, where it was demonstrated to have a central function in cellular osmoregulation. For archaea, currently little information on second messengers is available. This study proves that c‐di‐AMP is present in vivo in the archaeon Haloferax volcanii and demonstrates ...

Haloquadratum walsbyi gen. nov., sp. nov., the square haloarchaeon of Walsby, isolated from saltern crystallizers in Australia and Spain [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2007 Strains C23T and HBSQ001 were isolated from solar salterns and are novel square-shaped, aerobic, extremely halophilic members of the domain Archaea and family Halobacteriaceae. Cells stained Gram-negative and grew optimally in media containing 18 % salts at around neutral pH. Mg2+ is not required.

A Manual Curation Strategy to Improve Genome Annotation: Application to a Set of Haloarchael Genomes
Life, 2015 Genome annotation errors are a persistent problem that impede research in the biosciences. A manual curation effort is described that attempts to produce high-quality genome annotations for a set of haloarchaeal genomes (Halobacterium salinarum and Hbt ...

Archaea, Volume 2017, Issue 1, 2017., 2017 A 1.1 × 106 Da acidic exopolysaccharide (EPS) was purified from an extremely halophilic archaeon Haloarcula hispanica ATCC33960 with a production of 30 mg L−1 when grown in AS‐168 medium, which mainly composed of mannose and galactose with a small amount of glucose in a molar ratio of 55.9 : 43.2 : 0.9.

Archaea, Volume 2016, Issue 1, 2016., 2016 Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of ...

Crystal structures of a halophilic archaeal malate synthase from Haloferax volcanii and comparisons with isoforms A and G [PDF]
, 2011 Background Malate synthase, one of the two enzymes unique to the glyoxylate cycle, is found in all three domains of life, and is crucial to the utilization of two-carbon compounds for net biosynthetic pathways such as gluconeogenesis.

Precise Similarity of Many Human Proteins to Proteins of Prokarya [PDF]
, 2007 Proteins originated in early forms of life and have long survived, because they have always been required. Some recognizably similar proteins are found in all sequence comparisons between species, no matter how distant, including prokaryotes and ...

Diversity of the DNA Replication System in the Archaea Domain
Archaea, Volume 2014, Issue 1, 2014., 2014 The precise and timely duplication of the genome is essential for cellular life. It is achieved by DNA replication, a complex process that is conserved among the three domains of life. Even though the cellular structure of archaea closely resembles that of bacteria, the information processing machinery of archaea is evolutionarily more closely related ...

Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea [PDF]
, 2013 Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.
