CC -!- FUNCTION: Formation of phosphoenolpyruvate, which is the primary
CC acceptor of CO(2) in C4 and some Crassulacean acid metabolism plants.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + phosphate + pyruvate = AMP + diphosphate + H(+) +
CC phosphoenolpyruvate; Xref=Rhea:RHEA:10756, ChEBI:CHEBI:15361,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58702, ChEBI:CHEBI:456215; EC=2.7.9.1;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P11155};
CC -!- ACTIVITY REGULATION: Activated by light-induced dephosphorylation.
CC Inhibited by dark-induced phosphorylation. Both reactions are catalyzed
CC by PDRP1 (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC -!- DOMAIN: The N-terminal domain contains the ATP/Pi binding site, the
CC central domain the pyrophosphate/phosphate carrier histidine, and the
CC C-terminal domain the pyruvate binding site. {ECO:0000250}.
CC -!- PTM: Phosphorylation of Thr-530 in the dark inactivates the enzyme.
CC Dephosphorylation upon light stimulation reactivates the enzyme (By
CC similarity). {ECO:0000250}.
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 (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PEP-utilizing enzyme family. {ECO:0000305}.
