CC -!- FUNCTION: Catalyzes the phosphorylation of D-fructose 6-phosphate, the
CC first committing step of glycolysis. Uses inorganic phosphate (PPi) as
CC phosphoryl donor instead of ATP like common ATP-dependent
CC phosphofructokinases (ATP-PFKs), which renders the reaction reversible,
CC and can thus function both in glycolysis and gluconeogenesis.
CC Consistently, PPi-PFK can replace the enzymes of both the forward (ATP-
CC PFK) and reverse (fructose-bisphosphatase (FBPase)) reactions.
