What does PFP stand for? 

PFP

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: In plants, the PFP is located in the cytosol of the cell and is strongly activated by the signal molecule fructose 2,6-bisphosphate. ⁕ Fructose 6-phosphate ⁕ Fructose 1,6-bisphosphate PFP is an exclusively cytosolic enzyme that catalyses the phosphorylation of fructose-6-phosphate to fructose-1,6-bisphosphate in the glycolytic direction, and the de-phosphorylation of fructose-1,6-bisphoshate to fructose-6-phosphate in the gluconeogenic reaction. 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.
