WebAldolase is likely ubiquitous to all cells, with larger concentrations present in muscle, liver, and brain tissues. Increases in aldolase levels have been detected in myotonic muscle … WebThe fructose-bisphosphate aldolase, often called aldolase, is a glycolytic enzyme that catalyses the conversion of fructose 1-6-diphosphate to glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate via the glycolysis metabolic pathway.
WebJan 3, 2024 · The enzymes F-diP aldolase and triose-P-isomerase both catalyze freely reversible reactions. Also, both reactions proceed with a positive free energy change and are therefore endergonic. The sum of the free energy changes for the splitting of F1,6 diP into two G-3-Ps is a whopping +7.5 Kcal per mole, a very energetically unfavorable process. WebThe activity of the variants towards native substrates l-threonine and l-allo-threonine decreased by 2- to 10-fold in the retro-aldol reaction when compared with that of wild-type (WT) PASLD. In ...
