Function
function
Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate.
Catalytic activity
- ATP + shikimate = 3-phosphoshikimate + ADP + H+
Cofactor
Note: Binds 1 Mg2+ ion per subunit.
Pathway
Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 5/7.
