Diphosphate—fructose-6-phosphate 1-phosphotransferase also known as PFP is an enzyme of carbohydrate metabolism in plants and some bacteria. The enzyme () catalyses the reversible interconversion of fructose 6-phosphate and fructose 1,6-bisphosphate using inorganic pyrophosphate as the phosphoryl donor: :diphosphate + D-fructose 6-phosphate phosphate + D-fructose 1,6-bisphosphate In plants, the PFP is located in the cytosol of the cell and is strongly activated by the signal molecule fructose 2,6-bisphosphate.

Reeves first isolated PFP from ''Entamoeba histolytica'', a lower eukaryote. The first plant PFP isolated was from the leaves of pineapples by Carnal and Black and it has since been isolated from a variety of plant species and tissues. == Nomenclature == 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), * inorganic pyrophosphate-dependent phosphofructokinase, * inorganic pyrophosphate-phosphofructokinase, * pyrophosphate-dependent phosphofructo-1-kinase, and * pyrophosphate-fructose 6-phosphate 1-phosphotransferase, * pyrophosphate-fructose 6-phosphate phosphotransferase 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PFP (enzyme)」の詳細全文を読む スポンサード リンク
