Protein

Fructose-bisphosphate aldolase

Gene

fba

Organism
Helicobacter pylori (strain ATCC 700392 / 26695) (Campylobacter pylori)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.

Cofactori

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. Glucose-6-phosphate isomerase (pgi)
  3. no protein annotated in this organism
  4. Fructose-bisphosphate aldolase (fba)
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.
