May be involved in the metabolism of fructose-bisphosphate (beta-D-fructose 1,6-bisphosphate) and of fructose 1-phosphate. beta-D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-phosphate + dihydroxyacetone phosphate Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 4/4. Ubiquitous. All stages of development. Belongs to the class I fructose-bisphosphate aldolase family.
