General annotation (Comments)

Function

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 activity

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

Cofactor

Binds 2 zinc ions per subunit. One is catalytic and the other provides a structural contribution By similarity.

Pathway

Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 4/4.

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the class II fructose-bisphosphate aldolase family.
