General annotation (Comments)

Function

Catalyzes the specific phosphorylation of the 3-hydroxyl group of shikimic acid using ATP as a cosubstrate. Ref.3

Catalytic activity

ATP + shikimate = ADP + shikimate 3-phosphate. HAMAP MF_00109

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_00109

Pathway

Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 5/7. HAMAP MF_00109

Subunit structure

Monomer By similarity. HAMAP MF_00109

Subcellular location

Cytoplasm Probable HAMAP MF_00109.

Sequence similarities

Belongs to the shikimate kinase family.

Biophysicochemical properties
