CC   -!- FUNCTION: Catalyzes the specific phosphorylation of the 3-hydroxyl
CC       group of shikimic acid using ATP as a cosubstrate. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + shikimate = 3-phosphoshikimate + ADP + H(+);
CC         Xref=Rhea:RHEA:13121, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC         ChEBI:CHEBI:36208, ChEBI:CHEBI:145989, ChEBI:CHEBI:456216;
CC         EC=2.7.1.71;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000250};
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC       chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC       5/7.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- DOMAIN: Consists of three domains: the CORE domain which forms the
CC       binding site for nucleotides, the LID domain which closes over the
CC       active site upon ATP or shikimate binding, and the substrate-binding
CC       domain which functions to recognize and bind shikimate. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the shikimate kinase family. {ECO:0000305}.
