Characterization of the heat shock response inEnterococcus faecalis


We have characterized the general properties of the heat shock response of the Gram-positive hardy bacteriumEnterococcus faecalis. The heat resistance (60°C or 62.5°C, 30 min) of log phase cells ofE. faecalis grown at 37°C was enhanced by exposing cells to a prior heat shock at 45°C or 50°C for 30 min. These conditioning temperatures also induced ethanol (22%, v/v) tolerance. The onset of thermotolerance was accompanied by the synthesis of a number of heat shock proteins. The most prominent bands had molecular weights in the range of 48 to 94kDa. By Western blot analysis two of them were found to be immunologically related to the well known DnaK (72 kDa) and GroEL (63 kDa) heat shock proteins ofEscherichia coli. Four other proteins showing little or no variations after exposure to heat are related to DnaJ, GrpE and Lon (La)E. coli proteins and to theBacillus subtilis δ43 factor. Ethanol (2% or 4%, v/v) treatments elicited a similar response although there was a weaker induction of heat shock proteins than with heat shock.
