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:0000250|UniProtKB:P08839}.
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:0000250|UniProtKB:P08839};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:P08839};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P08839}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- DOMAIN: The N-terminal domain contains the HPr binding site, the
CC       central domain the pyrophosphate/phosphate carrier histidine, and the
CC       C-terminal domain the pyruvate binding site.
CC       {ECO:0000250|UniProtKB:P08839}.
CC   -!- MISCELLANEOUS: The reaction takes place in three steps, mediated by a
CC       phosphocarrier histidine residue located on the surface of the central
CC       domain. The two first partial reactions are catalyzed at an active site
CC       located on the N-terminal domain, and the third partial reaction is
CC       catalyzed at an active site located on the C-terminal domain. For
CC       catalytic turnover, the central domain swivels from the concave surface
CC       of the N-terminal domain to that of the C-terminal domain.
CC       {ECO:0000250|UniProtKB:P08839}.
CC   -!- SIMILARITY: Belongs to the PEP-utilizing enzyme family. {ECO:0000305}.
