Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate. ATP + shikimate = 3-phosphoshikimate + ADP + H(+) Binds 1 Mg(2+) ion per subunit. Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 5/7. Monomer. Expressed under the control of TyrR and TrpR repressors. The LID domain closes over the active site upon ATP binding. Two isozymes have been found in E.coli. AroK has 100-fold lower affinity for shikimate than AroL, suggesting that AroL is the dominant enzyme in the biosynthesis of the aromatic amino acids, with AroK playing a secondary role and possibly participating in an as yet unidentified cellular process. Belongs to the shikimate kinase family. AroL subfamily.
