An alkaline shift induces the heat shock response in Escherichia coli.


Activation of heat shock response was observed after an alkaline shift of extracellular pH: it peaked at 5 to 10 min, as was previously reported for the heat-induced response, and was dependent on a functional rpoH gene, which is the positive regulator of the heat shock response. An induction of over sixfold was observed for dnaK and groE. The response was… (More)
