Adaptations moléculaires de protéases isolées de bactéries du milieu antarctique


Enzymatic activity is strictly a function of temperature. In a number of organisms which possess no internal temperature regulation system, the internal metabolism parallels that of the environment by rising or falling with ambient temperature. The purpose of this work was to study molecular methods governing the adaptation of enzymes to functioning in cold conditions. The analysis of a model has allowed a number of specific adaptations to environment to be studied, specifically of a factor with greater flexibility allowing increased activity at low temperature.
