Accepted name: D-tagatose-1-phosphate kinase
Reaction: ATP + D-tagatopyranose 1-phosphate = ADP + D-tagatofuranose 1,6-bisphosphate
Other name(s): TagK
Systematic name: ATP:D-tagatopyranse-1-phosphate 6-phosphotransferase
Comments: The enzyme, which has been purified from the bacteria Klebsiella oxytoca and Bacillus licheniformis, is part of a D-tagatose catabolic pathway. The substrate, which occurs in a pyranose form in solution, undergoes a change to the furanose conformation after binding to the enzyme, in order to permit phosphorylation at C-6.
