Reactions Classified By Substrate Small-Molecule Reactions

EC Number:

Enzymes and Genes:
6-phosphofructokinase I Inferred from experiment : pfkA
6-phosphofructokinase II Inferred from experiment : pfkB

In Pathway: glycolysis II (from fructose 6-phosphate) , glycolysis I (from glucose 6-phosphate)

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: 6-phosphofructokinase

Enzyme Commission Synonyms: 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

This is a key control step in glycolysis [Uyeda79]

Enzyme Commission Summary:
D-Tagatose 6-phosphate and sedoheptulose 7-phosphate can act as acceptors. UTP, CTP and ITP can act as donors. Not identical with EC 6-phosphofructo-2-kinase.
