Gene
pfp, PFK2, pfpB, BB_0020
Organism
Borrelia burgdorferi (strain ATCC 35210 / B31 / CIP 102532 / DSM 4680)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of D-fructose 6-phosphate, the first committing step of glycolysis. Uses inorganic phosphate (PPi) as phosphoryl donor instead of ATP like common ATP-dependent phosphofructokinases (ATP-PFKs), which renders the reaction reversible, and can thus function both in glycolysis and gluconeogenesis. Consistently, PPi-PFK can replace the enzymes of both the forward (ATP-PFK) and reverse (fructose-bisphosphatase (FBPase)) reactions.1 Publication

Catalytic activityi

Diphosphate + D-fructose 6-phosphate = phosphate + D-fructose 1,6-bisphosphate.1 Publication
