In enzymology a tagatose kinase (EC 2.7.1.101) is an enzyme that catalyzes the chemical reactionATP + D-tagatose ADP + D-tagatose 6-phosphateThus 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 (phosphotransferases) with an alcohol group as acceptor.
