HUMAN MUSCLE FRUCTOSE 1,6-BISPHOSPHATE ALDOLASE COMPLEXED WITH FRUCTOSE 1,6-BISPHOSPHATE

Structural highlights

4ald is a 1 chain structure with sequence from Homo sapiens. The February 2004 RCSB PDB Molecule of the Month feature on The Glycolytic Enzymes by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:	Fructose-bisphosphate aldolase, with EC number 4.1.2.13
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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).

Publication Abstract from PubMed

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 flexible C-terminal region. This is also the region where the native and complex structures exhibit differences. The conformational changes between native and complex structure are not large, but the observed complex does not involve the full formation of the Schiff's base intermediate, and suggests a preliminary hydrogen-bonded Michaelis complex before the formation of the covalent complex.
