Multiple regions on the Escherichia coli heat shock transcription factor sigma32 determine core RNA polymerase binding specificity.

Journal of bacteriology - 1 Mar 1998

Joo D M, Nolte A, Calendar R, Zhou Y N, Jin D J

Abstract excerpt

We have analyzed the core RNA polymerase (RNAP) binding activity of the purified products of nine defective alleles of the rpoH gene, which encodes sigma32 in Escherichia coli. All mutations studied here lie outside of the putative core RNAP binding regions 2.1 and 2.2. Based on the estimated K(s)s for the mutant sigma and core RNAP interaction determined by in vitro transcription and by glycerol gradient...
