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. Is critical for plant growth and
CC development. {ECO:0000269|PubMed:21805151}.
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; Evidence={ECO:0000269|PubMed:21805151};
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. {ECO:0000305}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:P30613}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000269|PubMed:21805151}.
CC -!- TISSUE SPECIFICITY: Expressed in leaf mesophyll cells, phloem companion
CC cells in stems, cortical parenchyma cells in roots, glumes, anthers,
CC stigma and style of young florets, and milky stage seeds.
CC {ECO:0000269|PubMed:21805151}.
CC -!- DISRUPTION PHENOTYPE: Dwarf phenotype with panicle enclosure, reduced
CC seed set and outgrowth of axillary buds from culm nodes.
CC {ECO:0000269|PubMed:21805151}.
CC -!- SIMILARITY: Belongs to the pyruvate kinase family. {ECO:0000305}.
