Comparative roles of clpA and clpB in the survival of S. Typhimurium under stress and virulence in poultry.


ABSTRACT: By assisting in the proteolysis, disaggregation and refolding of the aggregated proteins, Caseinolytic proteases (Clps) enhance the cellular survival under stress conditions. In the current study, comparative roles of two such Clps, ClpA (involved in proteolysis) and ClpB (involved in protein disaggregation and refolding) in the survival of Salmonella Typhimurium (S. Typhimurium) under different stresses and in virulence have been investigated. clpA and clpB gene deletion mutant strains (?clpA and ?clpB) of S. Typhimurium have been hypersensitive to 42?°C, HOCl and paraquat. However, the ?clpB strain was comparatively much more susceptible (p?
