Structure, function and evolution of the Archaeal class I fructose-1,6-bisphosphate aldolase.
FBPA (fructose-1,6-bisphosphate aldolase) catalyses the reversible aldol condensation of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate to form fructose 1,6-bisphosphate. Two classes of FBPA, which rely on different reaction mechanisms, have so far been discovered, class I mainly found in Eucarya and class II mainly in Bacteria. Only recently were genes encoding proteins with FBPA ac...

متن کاملThe dhnA gene of Escherichia coli encodes a class I fructose bisphosphate aldolase.
The gene encoding the Escherichia coli Class I fructose-1, 6-bisphosphate aldolase (FBP aldolase) has been cloned and the protein overproduced in high amounts. This gene sequence has previously been identified as encoding an E. coli dehydrin in the GenBanktrade mark database [gene dhnA; entry code U73760; Close and Choi (1996) Submission to GenBanktrade mark]. However, the purified protein over...
متن کاملAffinity labeling of a previously undetected essential lysyl residue in class I fructose bisphosphate aldolase.
The affinity label N-bromoacetylethanolamine phosphate (BrAcNHEtOP) has been used previously at pH 6.5 to identify His-359 of rabbit muscle aldolase as an active site residue. We now find that the specificity of the reagent is pH-dependent. At pH 8.5, alkylation with 14C-labeled BrAcNHEtOP abolishes both fructose-1,6-P2 cleavage activity and transaldolase activity. The stoichiometry of incorpor...
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...
