How do bacteria survive these low temperatures?

The bacteria whether pathogenic or not, must adapt their growth to environmental changes, such as variations in temperature Researchers at CNRS (Lab Architecture reactivity and RNA), of the University of Camerino (Italy) and Dusseldorf ( Germany) have discovered that it is the structure of RNAtemperature and can thus translate the proteins necessary for the survival of bacteria. These results are published in the journal Molecular Cell, 15 January 2010.

It has already been shown that during a sudden drop in temperature, the process of transcription (producing RNA from DNA) and translation (protein production from mRNA) are strongly affected. However, low temperature, protein family CSpA (cold shock protein) are more numerous. These proteins called "cold adaptation" are from the translation of a dozen genes. These are protein "chaperone" DNA and RNA, they bind to nucleic acids and thus facilitate the most fundamental processes (transcription, translation, degradation of RNA, assembly of ribosomes ...)
