The fructose-1,6-bisphosphate aldolases: same reaction, different enzymes.
Two forms of the enzyme fructoseI ,6-bisphosphate aldolase (EC 4. I .2.13) are known, designated class I and class 11. The enzymes o f class I function by imine formation between the substrate and a catalytically essential lysine residue in the active site, which acts to stabilize the intermediate carbanion (for review, see [ I , 21). The enzymes of class I1 utilize a divalent metal ion to act ...
متن کاملCatabolism of fructose and mannitol in Clostridium thermocellum: presence of phosphoenolpyruvate: fructose phosphotransferase, fructose 1-phosphate kinase, phosphoenolpyruvate: mannitol phosphotransferase, and mannitol 1-phosphate dehydrogenase in cell extracts.
Fructose and mannitol are fermented by Clostridium thermocellum in a medium containing salts and 0.5% yeast extract. The initial reaction in the catabolism of fructose was found to be the formation of fructose l-phosphate by phosphoenolpyruvate (PEP):fructose phosphotransferase which resembles the Kundig-Roseman phosphotransferase system. The phosphorylation of fructose l-phosphate to form fruc...
متن کاملA conserved glutamate residue exhibits multifunctional catalytic roles in D-fructose-1,6-bisphosphate aldolases.
The aldolase catalytic cycle consists of a number of proton transfers that interconvert covalent enzyme intermediates. Glu-187 is a conserved amino acid that is located in the mammalian fructose-1,6-bisphosphate aldolase active site. Its central location, within hydrogen bonding distance of three other conserved active site residues: Lys-146, Glu-189, and Schiff base-forming Lys-229, makes it a...
متن کاملInactivation of class I fructose diphosphate aldolases by the substrate analog N-bromoacetylethanolamine phosphate.
N-Bromoacetylethanolamine phosphate, prepared by the bromoacetylation of ethanolamine phosphate, has been tested as an active site-specilic reagent for rabbit and rat muscle fructose diphosphate aldolases. The reagent inactivates both enzymes, and inactivation is prevented by substrates or competitive inhibitors. Loss of activity is pseudo-first order until the later stages of inactivation, and...
