Characterization and stability of ribosomes from mesophilic and thermophilic bacteria.
Ribosomes were isolated from three mesophilic and three thermophilic strains of Bacillus. The ribosomes consisted of about 55% protein and 45% ribonucleic acid. Average ratios for the absorbance at 260/235 and 260/280 mmu were 1.77 and 1.92 for the mesophiles and 1.63 and 1.84 for the thermophiles. Ultracentrifugation revealed mainly components with sedimentation coefficients of about 30, 50, 7...
متن کاملComparative analysis of DNA-binding proteins between thermophilic and mesophilic bacteria.
Thermophilic bacteria are one of the most attractive forms of life, and their adaptation mechanisms to elevated temperatures have been extensively studied over the years. Thermal adaptations of cell components such as proteins and RNA are well studied, but adaptations of interactions between these components must be also vital for the thermophiles. Protein-DNA interactions play crucial roles in...

15 صفحه اولPhysical bases of thermal stability of proteins: A comparative study on homologous pairs from mesophilic and thermophilic organisms
We used classical molecular dynamics simulation method to investigate physical factors responsible for the increased thermal stability of proteins from thermophilic and hyperthermophilic organisms. Subject of investigation were two pairs of homologous proteins from the functional classes of: 1) cold shock proteins from Escherichia coli (mesophilic) and Bacillus caldolyticus (thermophilic) and 2...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
