ACTIVITY AND SPECIFICITY OF HUMAN ALDOLASES
Structural highlights
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). Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe structure of the type I fructose 1,6-bisphosphate aldolase from human muscle has been extended from 3 A to 2 A resolution. The improvement in the resulting electron density map is such that the 20 or so C-terminal residues, known to be associated with activity and isozyme specificity, have been located. The side-chain of the Schiff's base-forming lysine 229 is located towards the centre of an eight-stranded beta-barrel type structure. The C-terminal "tail" extends from the rim of the beta-barrel towards lysine 229, thus forming part of the active site of the enzyme. This structural arrangement appears to explain the difference in activity and specificity of the three tissue-specific human aldolases and helps with our understanding of the type I aldolase reaction mechanism.
