摘要：

IIA(Ntr) 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 IIA(Ntr) influences sigma(54)-dependent transcription when the xylS operon is expressed in Escherichia coli. Loss of IIA(Ntr) influences, but does not abolish cyclic AMP-independent carbon catabolite repression.
