Tagatose kinase
In enzymology, a tagatose kinase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and D-tagatose, whereas its two products are ADP and D-tagatose 6-phosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:D-tagatose 6-phosphotransferase. Other names in common use include tagatose 6-phosphate kinase , D-tagatose 6-phosphate kinase, and tagatose-6-phosphate kinase. This enzyme participates in galactose metabolism.
