Positive supercoiling in thermophiles and mesophiles: of the good and evil.
DNA supercoiling plays essential role in maintaining proper chromosome structure, as well as the equilibrium between genome dynamics and stability under specific physicochemical and physiological conditions. In mesophilic organisms, DNA is negatively supercoiled and, until recently, positive supercoiling was considered a peculiar mark of (hyper)thermophilic archaea needed to survive high temper...
متن کاملComparison of evolutionary characteristics of orthologous sets from halophiles, thermophiles and mesophiles
Molecular evolution is the change of amino acid composition at locus specific positions of proteins for maintaining structural and functional integrity over long periods of time. In orthologous protein sets, adapted in different environmental conditions such as normal, high temperature and high ionic condition might have different or identical evolutionary characters. To understand the basis of...
متن کاملComparative analysis of amino acid sequences from mesophiles and thermophiles in respective of carbon–nitrogen hydrolase family
A comparative study of amino acid sequence and physicochemical properties indicates the affiliation of protein from the nitrilase/cyanide hydratase family. This family contains nitrilases that break carbon-nitrogen bonds and appear to be involved in the reduction of organic nitrogen compounds and ammonia production. They all have distinct substrate specificity and include nitrilase, cyanide hyd...
متن کاملIntercellular Bridges as Protoplasmic Anastomoses between Smooth Muscle Cells
In electron microscopic studies, protoplasmic anastomoses were found to occur between smooth muscle cells in the gastrointestinal tracts of rats. The protoplasmic connections are apparently cylindrical in form and contain cytoplasm having a density similar to that of the cellular regions connected. The membranes enclosing the cytoplasmic connections are continuous with the membranes of the conn...
