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.
IIANtr编码于许多革兰氏阴性菌的rpoN操纵子中，是磷酸烯醇丙酮酸：糖磷酸转移酶系统中一类磷酸转移蛋白的同源物。我们利用恶臭假单胞菌TOL质粒上的xylS操纵子 - lacZ融合基因，证明当xylS操纵子在大肠杆菌中表达时，IIANtr会影响σ54依赖性转录。IIANtr的缺失会影响，但不会消除不依赖环磷酸腺苷的碳代谢物阻遏。
