In enzymology, a shikimate kinase (EC 2.7.1.71) is an enzyme that catalyzes the chemical reaction

ATP + shikimate ADP + shikimate 3-phosphate

Thus, the two substrates of this enzyme are ATP and shikimate, whereas its two products are ADP and shikimate 3-phosphate.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:shikimate 3-phosphotransferase. Other names in common use include shikimate kinase (phosphorylating), and shikimate kinase II. This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis.
