Posttranscriptional activation of the transcriptional activator Rob by dipyridyl in Escherichia coli.


The transcriptional activator Rob consists of an N-terminal domain (NTD) of 120 amino acids responsible for DNA binding and promoter activation and a C-terminal domain (CTD) of 169 amino acids of unknown function. Although several thousand molecules of Rob are normally present per Escherichia coli cell, they activate promoters of the rob regulon poorly. We… (More)
