Mutation analysis of the 5' untranslated region of the cold shock cspA mRNA of Escherichia coli.


The mRNA for CspA, a major cold shock protein in Escherichia coli, contains an unusually long (159 bases) 5' untranslated region (5'-UTR), and its stability has been shown to play a major role in cold shock induction of CspA. The 5'-UTR of the cspA mRNA has a negative effect on its expression at 37 degrees C but has a positive effect upon cold shock. In… (More)
