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}.
