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. Belongs to the shikimate kinase family. Extended N-terminus. Extended N-terminus.
