In enzymology, a tagatose-6-phosphate kinase (EC 2.7.1.144) is an enzyme that catalyzes the chemical reaction
ATP + D-tagatose 6-phosphate
Thus, the two substrates of this enzyme are ATP and D-tagatose 6-phosphate, whereas its two products are ADP and D-tagatose 1,6-bisphosphate.
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:D-tagatose-6-phosphate 1-phosphotransferase. This enzyme participates in galactose metabolism.
Structural studies
As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes 2AWD, 2F02, 2JG1, 2JGV, and 2Q5R.
