Fructose-bisphosphate aldolase

Anabaena sp. (strain L31)
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli


Catalyzes the aldol condensation of dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with glyceraldehyde 3-phosphate (G3P) to form fructose 1,6-bisphosphate (FBP) in gluconeogenesis and the reverse reaction in glycolysis.By similarity

Catalytic activityi

D-fructose 1,6-bisphosphate = glycerone phosphate + D-glyceraldehyde 3-phosphate.By similarity


Zn2+By similarityNote: Binds 2 Zn2+ ions per subunit. One is catalytic and the other provides a structural contribution.By similarity

Pathwayi: glycolysis

This protein is involved in step 4 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. no protein annotated in this organism
  4. Fructose-bisphosphate aldolase
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.
