title: sigma54-dependent transcription of the Pseudomonas putida xylS operon is influenced by the IIANtr protein of the phosphotransferase system in Escherichia coli.
abstract: IIANtr, encoded within the rpoN operons of many Gram-negative bacteria, is a homologue of a class of phosphoryl transfer proteins of the phosphoenolpyruvate: sugar phosphotransferase system. We have used a xylS operon-lacZ fusion from the TOL plasmid of Pseudomonas putida to show that IIANtr influences sigma 54-dependent transcription when the xylS operon is expressed in Escherichia coli. Loss of IIANtr influences, but does not abolish cyclic AMP-independent carbon catabolite repression.
