Diphosphate-fructose-6-phosphate 1-phosphotransferase

In enzymology, a diphosphate-fructose-6-phosphate 1-phosphotransferase is an enzyme that catalyzes the chemical reaction


 * diphosphate + D-fructose 6-phosphate $$\rightleftharpoons$$ phosphate + D-fructose 1,6-bisphosphate

Thus, the two substrates of this enzyme are diphosphate and D-fructose 6-phosphate, whereas its two products are phosphate and D-fructose 1,6-bisphosphate.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is diphosphate:D-fructose-6-phosphate 1-phosphotransferase. Other names in common use include 6-phosphofructokinase (pyrophosphate), pyrophosphate-fructose 6-phosphate 1-phosphotransferase, inorganic pyrophosphate-dependent phosphofructokinase, inorganic pyrophosphate-phosphofructokinase, pyrophosphate-dependent phosphofructo-1-kinase, and pyrophosphate-fructose 6-phosphate phosphotransferase. This enzyme participates in fructose and mannose metabolism.
