Thermotropic Properties of Thermophilic, Mesophilic, and Psychrophilic Blue-green Algae.
Thermotropic properties of blue-green algae grown at high, room, and low temperatures in H(2)O and D(2)O media were studied by highly sensitive differential scanning microcalorimetry. The thermograms of these organisms contain an endothermal peak in the temperature range of 50 to 70 C with an endothermal heat ranging from 0.14 to 1.91 joules per gram organism. The temperature at which the endot...
متن کاملRibosomes, polyribosomes, and deoxyribonucleic acid from thermophilic mesophilic, and psychrophilic clostridia.
Analysis of deoxyribonucleic acid (DNA) from four species of Clostridium, including two thermophiles, a mesophile, and a psychrophile, revealed no obvious relationship between growth temperature and DNA base composition. The melting temperatures (T(m)) of the DNA from the four species varied no more among the thermophilic, mesophilic, and psychrophilic species than among many related mesophilic...
متن کاملStructures and analysis of highly homologous psychrophilic, mesophilic, and thermophilic adenylate kinases.
The crystal structures of adenylate kinases from the psychrophile Bacillus globisporus and the mesophile Bacillus subtilis have been solved and compared with that from the thermophile Bacillus stearothermophilus. This is the first example we know of where a trio of protein structures has been solved that have the same number of amino acids and a high level of identity (66-74%) and yet come from...
متن کاملStructural and functional adaptations to extreme temperatures in psychrophilic, mesophilic, and thermophilic DNA ligases.
Psychrophiles, host of permanently cold habitats, display metabolic fluxes comparable to those exhibited by mesophilic organisms at moderate temperatures. These organisms have evolved by producing, among other peculiarities, cold-active enzymes that have the properties to cope with the reduction of chemical reaction rates induced by low temperatures. The emerging picture suggests that these enz...
متن کاملTemperature adaptations in psychrophilic, mesophilic and thermophilic chloride-dependent alpha-amylases.
The functional and structural adaptations to temperature have been addressed in homologous chloride-dependent α-amylases from a psychrophilic Antarctic bacterium, the ectothermic fruit fly, the homeothermic pig and from a thermophilic actinomycete. This series covers nearly all temperatures encountered by living organisms. We report a striking continuum in the functional properties of these enz...
