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. Enzyme I transfers the
CC phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl
CC carrier protein (HPr). {ECO:0000256|ARBA:ARBA00002728,
CC ECO:0000256|PIRNR:PIRNR000732}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-histidyl-[protein] + phosphoenolpyruvate = N(pros)-phospho-
CC L-histidyl-[protein] + pyruvate; Xref=Rhea:RHEA:23880, Rhea:RHEA-

CC Evidence={ECO:0000256|ARBA:ARBA00000683,
CC ECO:0000256|PIRNR:PIRNR000732};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|PIRNR:PIRNR000732, ECO:0000256|PIRSR:PIRSR000732-3};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|PIRNR:PIRNR000732}.
CC -!- SIMILARITY: Belongs to the PEP-utilizing enzyme family.
CC {ECO:0000256|ARBA:ARBA00007837, ECO:0000256|PIRNR:PIRNR000732}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
