CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC       Note=Binds 1 Mg(2+) ion per subunit.;
CC   -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis;
CC       chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step
CC       5/7.
CC   -!- SUBUNIT: Monomer.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- DOMAIN: The LID domain closes over the active site upon ATP binding.
CC   -!- SIMILARITY: Belongs to the shikimate kinase family. AroL subfamily.

Comments: Mg(2+) is six-coordinated in shikimate kinase 1 (aroK, MF_00109)
 with direct interaction with two protein side-chains, whereas it is
 four-coordinated in shikimate kinase 2 (aroL, MF_01269) with direct
 interaction with only one protein side-chain.
