| - | Fructose 1,6-bisphosphate aldolase catalyzes the reversible cleavage of, fructose 1,6-bisphosphate and fructose 1-phosphate to dihydroxyacetone, phosphate and either glyceraldehyde 3-phosphate or glyceraldehyde, respectively. Catalysis involves the formation of a Schiff's base, intermediate formed at the epsilon-amino group of Lys229. The existing, apo-enzyme structure was refined using the crystallographic free-R-factor, and maximum likelihood methods that have been shown to give improved, structural results that are less subject to model bias. Crystals were also, soaked with the natural substrate (fructose 1,6-bisphosphate), and the, crystal structure of this complex has been determined to 2.8 A. The apo, structure differs from the previous Brookhaven-deposited structure (1ald), in the ... [[http://ispc.weizmann.ac.il/pmbin/getpm?10048322 (full description)]]

Disease
ALDOA_HUMAN Defects in ALDOA are the cause of glycogen storage disease type 12 (GSD12) [MIM:611881; also known as red cell aldolase deficiency. A metabolic disorder associated with increased hepatic glycogen and hemolytic anemia. It may lead to myopathy with exercise intolerance and rhabdomyolysis.[1] [2] [3] [4] [5]
Function
ALDOA_HUMAN Plays a key role in glycolysis and gluconeogenesis. In addition, may also function as scaffolding protein (By similarity).
