1. On the role of ppGpp and DksA mediated control of σ54-dependent transcription
Abstract : The σ54-dependent Po promoter drives transcription of an operon that encodes a suite of enzymes for (methyl)phenols catabolism. Transcription from Po is controlled by the sensor-activator DmpR that binds (methyl)phenol effectors to take up its active form. READ MORE

2. On the role of small regulatory molecules in the interplay between σ54- and σ70-dependent transcription
Abstract : Signal responsive transcriptional control in bacteria is mediated through both specific and global regulatory circuits to attune promoter output to prevailing conditions. Divergent transcription of a regulatory gene and a cognate promoter under its control provides an opportunity for interplay between transcription dependent on RNA polymerases utilizing various σ-factors, each of which programs the holoenzyme to recognize different classes of promoters.
