Temperature sensors of eubacteria.
In their natural habitats, bacteria are frequently exposed to sudden changes in temperature. It has been shown that bacteria use different strategies to cope with temperature changes. These strategies are genetically determined and start with registration of the temperature followed by the induction of a subset of genes allowing them to adapt to the stressful situation. Four different mechanisms have evolved termed the high and the low temperature response and the heat and the cold shock response. These temperature changes are registered by three different thermosensors: DNA, RNA and protein.
