Differential regulation of Ota and Otb, two primary glycine betaine transporters in the methanogenic archaeon Methanosarcina mazei go1 [PDF]
, 2008 Methanogenic archaea accumulate glycine betaine in response to hypersalinity, but the regulation of proteins involved, their mechanism of activation and regulation of the corresponding genes are largely unknown.

Investigating Abiotic and Biotic Mechanisms of Pyrite Reduction
Frontiers in Microbiology, 2022 Pyrite (FeS2) has a very low solubility and therefore has historically been considered a sink for iron (Fe) and sulfur (S) and unavailable to biology in the absence of oxygen and oxidative weathering.

Satellites in the prokaryote world [PDF]
, 2019 Background Satellites or tandem repeats are very abundant in many eukaryotic genomes. Occasionally they have been reported to be present in some prokaryotes, but to our knowledge there is no general comparative study on their occurrence.

Characterization of Methanosarcina barkeri MST and 227, Methanosarcina mazei S-6T, and Methanosarcina vacuolata Z-761T [PDF]
International Journal of Systematic Bacteriology, 1991 Members of the genus Methanosarcina are recognized as major aceticlastic methanogens, and several species which thrive in low-salt, pH-neutral culture medium at mesophilic temperatures have been described. However, the environmental conditions which support the fastest growth of these species (Methanosarcina barkeri MST [T = type strain] and 227 ...

Angewandte Chemie, Volume 137, Issue 36, September 1, 2025.A new genetically encoded amino acid is chemically converted into homocysteine (Hcy) under mild conditions to probe and to activate protein active sites. Surprisingly, Hcy can replace cysteine or serine residues in several enzymes. Its potential for a widespread use in proteins is further underlined by rendering Escherichia coli dependent on Hcy ...

Dual RNase and β-lactamase Activity of a Single Enzyme Encoded in Archaea
Life, 2020 β-lactam antibiotics have a well-known activity which disturbs the bacterial cell wall biosynthesis and may be cleaved by β-lactamases. However, these drugs are not active on archaea microorganisms, which are naturally resistant because of the lack of β ...

Transposase interaction with the β sliding clamp: Effects on insertion sequence proliferation and transposition rate [PDF]
, 2015 Insertion sequences (ISs) are ubiquitous and abundant mobile genetic elements in prokaryotic genomes. ISs often encode only one protein, the transposase, which catalyzes their transposition.

Distribution of methanogenic potential in fractions of turf grass used as inoculum for the start-up of thermophilic anaerobic digestion [PDF]
, 2012 This study aims to investigate thermophilic methanogens in turf used as an inoculum. Results showed that Methanoculleus sp. regarded as hydrogenotrophic and Methanosarcina sp. regarded as acetoclastic methanogens were present in turf tested.

Direct Interspecies Electron Transfer Mediated by Graphene Oxide-Based Materials
Frontiers in Microbiology, 2020 Conductive materials are known to promote direct interspecies electron transfer (DIET) by electrically bridging microbial cells. Previous studies have suggested that supplementation of graphene oxide (GO) based materials, including GO, and reduced GO ...
