  • Title: sigma54-dependent transcription of the Pseudomonas putida xylS operon is influenced by the IIANtr protein of the phosphotransferase system in Escherichia coli.
    Author: Du Y, Holtel A, Reizer J, Saier MH.
    Journal: Res Microbiol; 1996; 147(3):129-32. PubMed ID: 8761731.
    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.
