Protein

Pyrophosphate--fructose 6-phosphate 1-phosphotransferase

Gene

pfp

Organism
Frankia casuarinae (strain DSM 45818 / CECT 9043 / CcI3)
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

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.UniRule annotation

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.UniRule annotation

Catalytic activityi

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

Pathwayi: glycolysis

This protein is involved in step 3 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.UniRule annotationSAAS annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Glucose-6-phosphate isomerase (pgi)
  3. Pyrophosphate--fructose 6-phosphate 1-phosphotransferase (pfp), ATP-dependent 6-phosphofructokinase (pfkA), ATP-dependent 6-phosphofructokinase (pfkA), Pyrophosphate--fructose 6-phosphate 1-phosphotransferase (pfp)
  4. no protein annotated in this organism
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose, the pathway glycolysis and in Carbohydrate degradation.
