CC   -!- FUNCTION: Component of the phosphoenolpyruvate-dependent nitrogen-
CC       metabolic phosphotransferase system (nitrogen-metabolic PTS), that
CC       seems to be involved in regulating nitrogen metabolism. The phosphoryl
CC       group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl
CC       carrier protein NPr by enzyme I-Ntr. Phospho-NPr then transfers it to
CC       EIIA-Ntr. Could function in the transcriptional regulation of sigma-54
CC       dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr
CC       (PtsN) proteins. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HPr family. {ECO:0000305}.
