WebRpoH (ς 32) suppressors of the dnaK mutant with restored levels of RpoS and dnaK rpoS double mutants were used to show that DnaK plays both an independent and an RpoS-dependent role in starvation-induced thermotolerance. The results suggest that DnaK coordinates sigma factor levels in glucose-starved E. coli. WebRpoH is the heat-shock sigma factor in G. sulfurreducens ( Ueki and Lovley, 2007). Expression of the rpoH gene was induced by heat shock from 30 to 42 °C and appears to …
