Chromatin Structure and Dynamics in Hot Environments: Architectural Proteins and DNA Topoisomerases of Thermophilic Archaea
In all organisms of the three living domains (Bacteria, Archaea, Eucarya) chromosome-associated proteins play a key role in genome functional organization. They not only compact and shape the genome structure, but also regulate its dynamics, which is essential to allow complex genome functions. Elucidation of chromatin composition and regulation is a critical issue in biology, because of the in...
متن کاملCell cycle characteristics of thermophilic archaea.
We have performed a cell cycle analysis of organisms from the Archaea domain. Exponentially growing cells of the thermophilic archaea Sulfolobus solfataricus and Sulfolobus acidocaldarius were analyzed by flow cytometry, and several unusual cell cycle characteristics were found. The cells initiated chromosome replication shortly after cell division such that the proportion of cells with a singl...
متن کاملDistribution of archaea in a black smoker chimney structure.
Archaeal community structures in microhabitats in a deep-sea hydrothermal vent chimney structure were evaluated through the combined use of culture-independent molecular analyses and enrichment culture methods. A black smoker chimney was obtained from the PACMANUS site in the Manus Basin near Papua New Guinea, and subsamples were obtained from vertical and horizontal sections. The elemental com...
متن کاملAlcohol dehydrogenases from thermophilic and hyperthermophilic archaea and bacteria.
Many studies have been undertaken to characterise alcohol dehydrogenases (ADHs) from thermophiles and hyperthermophiles, mainly to better understand their activities and thermostability. To date, there are 20 thermophilic archaeal and 17 thermophilic bacterial strains known to have ADHs or similar enzymes, including the hypothetical proteins. Some of these thermophiles are found to have multipl...
متن کاملWidespread Disulfide Bonding in Proteins from Thermophilic Archaea
Disulfide bonds are generally not used to stabilize proteins in the cytosolic compartments of bacteria or eukaryotic cells, owing to the chemically reducing nature of those environments. In contrast, certain thermophilic archaea use disulfide bonding as a major mechanism for protein stabilization. Here, we provide a current survey of completely sequenced genomes, applying computational methods ...
