N2 - 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 induced by the alkalization of extracellular pH but not by the alkalization of intracellular pH. An acidic shift of extracellular pH failed to activate the heat shock response, showing that the response is specific to the alkaline shift.
