CC   -!- FUNCTION: Key regulatory enzyme of the glycolytic pathway that
CC       catalyzes the final step of glycolysis, converting ADP and
CC       phosphoenolpyruvate (PEP) to ATP and pyruvate by essentially
CC       irreversible transphosphorylation. {ECO:0000250|UniProtKB:Q2RAK2}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + pyruvate = ADP + H(+) + phosphoenolpyruvate;
CC         Xref=Rhea:RHEA:18157, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:58702, ChEBI:CHEBI:456216;
CC         EC=2.7.1.40;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:Q9LIK0};
CC   -!- COFACTOR:
CC       Name=K(+); Xref=ChEBI:CHEBI:29103;
CC         Evidence={ECO:0000250|UniProtKB:Q9LIK0};
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC       glyceraldehyde 3-phosphate: step 5/5.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:P30613}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:Q2RAK2}.
CC   -!- SIMILARITY: Belongs to the pyruvate kinase family. {ECO:0000305}.
