RNA polymerase beta' subunit: a target of DNA binding-independent activation.
The bacteriophage N4 single-stranded DNA binding protein (N4SSB) activates transcription by the Escherichia coli final sigma70-RNA polymerase at N4 late promoters. Here it is shown that the single-stranded DNA binding activity of N4SSB is not required for transcriptional activation. N4SSB interacts with the carboxyl terminus of the RNA polymerase beta' subunit in a region that is highly conserved in the largest subunits of prokaryotic and eukaryotic RNA polymerases.
