CC   -!- FUNCTION: General (non sugar-specific) component of the
CC       phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar
CC       PTS). This major carbohydrate active-transport system catalyzes the
CC       phosphorylation of incoming sugar substrates concomitantly with their
CC       translocation across the cell membrane. The phosphoryl group from
CC       phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier
CC       protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA
CC       domain. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HPr family. {ECO:0000305}.
