Resumo
The gram-positive bacterium Corynebacterium pseudotuberculosis is the causative agent of different diseases that cause dramatically reduced yields of wool and milk, and results in weight loss, carcass condemnation and also death mainly in sheep, equids, cattle and goats and therefore globally results in considerable economical loss. Cold shock proteins are conserved in many bacteria and eukaryotic cells and they help to restore normal cell functions after cold shock in which some appear to have specific functions at normal growth temperature as well.Cold shock protein A from C pseudotuberculosis was expressed in Escherichia coli and purified. The thermal unfolding/refolding process characterized by circular dichroism, differential scanning calorimetry and NMR spectroscopy techniques indicated that the refolding process was almost completely reversible.
