2.7.1.11

Accepted name:

6-phosphofructokinase

Reaction:

ATP + β-D-fructofuranose 6-phosphate = ADP + β-D-fructofuranose 1,6-bisphosphate

Other name(s):

phosphohexokinase; phosphofructokinase I; phosphofructokinase (phosphorylating); 6-phosphofructose 1-kinase; ATP-dependent phosphofructokinase; D-fructose-6-phosphate 1-phosphotransferase; fructose 6-phosphate kinase; fructose 6-phosphokinase; nucleotide triphosphate-dependent phosphofructokinase; phospho-1,6-fructokinase; PFK

Systematic name:

ATP:β-D-fructose-6-phosphate 1-phosphotransferase

Comments:

The enzyme from rabbit muscle displays absolute stereoselectivity for the β-anomer of D-fructofuranose 6-phosphate [9-11]. D-Tagatose 6-phosphate and sedoheptulose 7-phosphate can act as acceptors. UTP, CTP and ITP can act as donors. Not identical with EC 2.7.1.105 6-phosphofructo-2-kinase.
