Organism
Equus caballus (Horse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.UniRule annotation

Catalytic activityi

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

Cofactori

Mg2+UniRule annotation

Enzyme regulationi

Allosterically activated by ADP, AMP, or fructose 2,6-bisphosphate, and allosterically inhibited by ATP or citrate.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 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, Glucose-6-phosphate isomerase (GPI)
  3. ATP-dependent 6-phosphofructokinase (PFKP), ATP-dependent 6-phosphofructokinase (PFKM), ATP-dependent 6-phosphofructokinase (PFKL), ATP-dependent 6-phosphofructokinase, muscle type (PFKM)
  4. Fructose-bisphosphate aldolase (ALDOA), Fructose-bisphosphate aldolase, Fructose-bisphosphate aldolase (ALDOB), Fructose-bisphosphate aldolase (ALDOC)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
