2.7.1.90

Accepted name:

diphosphate—fructose-6-phosphate 1-phosphotransferase

Reaction:

diphosphate + D-fructose 6-phosphate = phosphate + D-fructose 1,6-bisphosphate

Other name(s):

6-phosphofructokinase (pyrophosphate); pyrophosphate-fructose 6-phosphate 1-phosphotransferase; inorganic pyrophosphate-dependent phosphofructokinase; inorganic pyrophosphate-phosphofructokinase; pyrophosphate-dependent phosphofructo-1-kinase; pyrophosphate-fructose 6-phosphate phosphotransferase

Systematic name:

diphosphate:D-fructose-6-phosphate 1-phosphotransferase

Comments:

The enzyme catalyses a similar reaction to EC 2.7.1.11, 6-phosphofructokinase, but utilizes diphosphate instead of ATP as the the phosphate donor. It has been described in higher plants, primitive eukaryotes, bacteria, and archaea.
