Activation of Chloroplast NADP-linked Glyceraldehyde-3-Phosphate Dehydrogenase by the Ferredoxin/Thioredoxin System.
NADP-glyceraldehyde-3-P dehydrogenase of spinach (Spinacia oleracea) chloroplasts was activated by thioredoxin that was reduced either photochemically with ferredoxin and ferredoxin-thioredoxin reductase or chemically with dithiothreitol. The activation process that was observed with the soluble protein fraction from chloroplasts and with the purified regulatory form of the enzyme was slow rela...
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...
متن کاملMechanism of glyceraldehyde-3-phosphate dehydrogenase inactivation by tyrosine nitration.
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a multifaceted protein that is involved in numerous processes including glycolysis, translational silencing, transcriptional regulation of specific genes, and acting as a nitric oxide sensor. The precise mechanism on how GAPDH is targeted to these different roles is unclear but believed to involve specific posttranslational modification to the...
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 کاملProkaryotic Expression and Serodiagnostic Potential of Glyceraldehyde-3-Phosphate Dehydrogenase and Thioredoxin Peroxidase from Baylisascaris schroederi
Baylisascaris schroederi, a roundworm parasite of giant pandas, badly affects the health of its hosts. Diagnosis of this disease currently depends mainly on sedimentation floatation and Polymerase Chain Reaction (PCR) methods to detect the eggs. However, neither of these methods is suitable for diagnosis of early-stage panda baylisascariasis and no information on early diagnosis of this disease...
