Tagatose/fructose phosphokinase (IPR017583)

Short name: Tagatose/fructose_Pkinase

Overlapping homologous superfamilies

Family relationships


This entry represents a family of hexose kinases that includes the tagatose-6-kinases from the carbohydrate kinase PfkB family (LacC subfamily), 1-phosphofructokinases and 6-phosphofructokinases isozyme 2 from the carbohydrate kinase PfkB family.

Fructose 1-phosphate kinase (also known as 1-phosphofructokinase) acts in concert with the fructose-specific phosphotransferase system (PTS), which phosphorylates fructose during transport to fructose-1-phosphate. The action of 1-phosphofructokinase results in beta-D-fructose-1,6-bisphosphate and is an entry point into glycolysis [PMID: 22493022] (GenProp0688).

Agatose-6-phosphate kinase (EC: is part of the tagatose-6-phosphate pathway of lactose degradation.
