Functional consequences of piceatannol binding to glyceraldehyde-3-phosphate dehydrogenase
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is one of the key redox-sensitive proteins whose activity is largely affected by oxidative modifications at its highly reactive cysteine residue in the enzyme's active site (Cys149). Prolonged exposure to oxidative stress may cause, inter alia, the formation of intermolecular disulfide bonds leading to accumulation of GAPDH aggregates and ultimat...
متن کاملOn the functional diversity of glyceraldehyde-3-phosphate dehydrogenase: biochemical mechanisms and regulatory control.
BACKGROUND New studies provide evidence that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is not simply a classical glycolytic protein of little interest. Instead, it is a multifunctional protein with significant activity in a number of fundamental cell pathways. GAPDH is a highly conserved gene and protein, with a single mRNA transcribed from a unique gene. Control mechanisms must exist wh...
متن کاملMutant analysis of glyceraldehyde 3-phosphate dehydrogenase in Escherichia coli.
NAD(+)-specific glyceraldehyde 3-phosphate dehydrogenase (EC 1.2.1.12) from Escherichia coli was purified to homogeneity by a relatively simple procedure involving affinity chromatography on agarose-hexane-NAD(+) and repeated crystallization. Rabbit antiserum directed against this protein produced one precipitin line in double-diffusion studies against the pure enzyme, and two lines against cru...
متن کاملMechanism of glyceraldehyde-3-phosphate transfer from aldolase to glyceraldehyde-3-phosphate dehydrogenase.
The catalytic interaction of glyceraldehyde-3-phosphate dehydrogenase with glyceraldehyde 3-phosphate has been examined by transient-state kinetic methods. The results confirm previous reports that the apparent Km for oxidative phosphorylation of glyceraldehyde 3-phosphate decreases at least 50-fold when the substrate is generated in a coupled reaction system through the action of aldolase on f...
متن کاملAcetyl phosphate formation catalyzed by glyceraldehyde-3-phosphate dehydrogenase.
Glyceraldehyde-3-phosphate dehydrogenase catalyzes the oxidative phosphorylation of n-glyceraldehyde-3-phosphate to 1,3-diphosphoglyceric acid (1, 2). The enzyme also catalyzes the oxidation of n-glyceraldehyde, although the product of this reaction has not been characterized (1,2). In the present study it is shown that acetaldehyde (3), propionaldehyde, and butyraldehyde also act as substrates...
