Cytosolic aldolase catalyzes the cleavage of D-fructose 1,6-bisphosphate to yield dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate. The active form of aldolase is a homotetramer. Three aldolase isozymes have been identified which differ in their patterns of expression in various adult tissues and during development but are otherwise functionally indistinguishable (Ali and Cox 1995; Freemont et al. 1984, 1988).
