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|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 COMP:9745, Rhea:RHEA-COMP:9746, ChEBI:CHEBI:15361, ChEBI:CHEBI:29979,
CC ChEBI:CHEBI:58702, ChEBI:CHEBI:64837; EC=2.7.3.9;
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.
