| Abstract |
In this study, we characterized the DnaK chaperone system from Tetragenococcus halophilus, a halophilic lactic acid bacterium. An in vivo complementation test showed that under heat stress conditions, T. halophilus DnaK did not rescue the growth of the Escherichia coli dnaK deletion mutant, whereas T. halophilus DnaJ and GrpE complemented the corresponding mutations of E. coli. Purified T. halophilus DnaK showed intrinsic weak ATPase activity and holding chaperone activity in vitro, but T. halophilus DnaK did not cooperate with the purified DnaJ and GrpE from either T. halophilus or E. coli in ATP hydrolysis or luciferase-refolding reactions under the conditions tested. E. coli DnaK, however, cross-reacted with those from both bacteria. This difference in the cooperation with DnaJ and GrpE appears to result in an inability of T. halophilus DnaK to replace the in vivo function of the DnaK chaperone of E. coli.
