Structural insights into the substrate binding and stereoselectivity of giardia fructose-1,6-bisphosphate aldolase.
Giardia lamblia fructose-1,6-bisphosphate aldolase (FBPA) is a member of the class II zinc-dependent aldolase family that catalyzes the cleavage of d-fructose 1,6-bisphosphate (FBP) into dihydroxyacetone phosphate (DHAP) and d-glyceraldehyde 3-phosphate (G3P). In addition to the active site zinc, the catalytic apparatus of FBPA employs an aspartic acid, Asp83 in the G. lamblia enzyme, which whe...

متن کاملCharacterization, kinetics, and crystal structures of fructose-1,6-bisphosphate aldolase from the human parasite, Giardia lamblia.
Class I and class II fructose-1,6-bisphosphate aldolases (FBPA), glycolytic pathway enzymes, exhibit no amino acid sequence homology and utilize two different catalytic mechanisms. The mammalian class I FBPA employs a Schiff base mechanism, whereas the human parasitic protozoan Giardia lamblia class II FBPA is a zinc-dependent enzyme. In this study, we have explored the potential exploitation o...
متن کاملIntracellular localization of fructose 1,6-bisphosphate aldolase.
Submission of a rat liver homogenate made in 250 mM sucrose-1 mM EDTA to centrifugation between 9,500 times g for 10 min and 105,000 times g for 60 min results in the sedimentation of 60 to 70% of the total cellular fructose 1,6-bisphosphate aldolase (EC 4.1.2.13). Under these conditions only about one-quarter of the total triose phosphate dehydrogenase and phosphoglycerate kinase appears in th...
متن کاملStructure of fructose bisphosphate aldolase from Bartonella henselae bound to fructose 1,6-bisphosphate
Fructose bisphosphate aldolase (FBPA) enzymes have been found in a broad range of eukaryotic and prokaryotic organisms. FBPA catalyses the cleavage of fructose 1,6-bisphosphate into glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. The SSGCID has reported several FBPA structures from pathogenic sources, including the bacterium Brucella melitensis and the protozoan Babesia bovis. Bioinf...
