Malate-aspartate-shuttle
WebThe malate-aspartate shuttle system is important in transporting NADH, produced during glycolysis in the cytosol into the mitochondria. NADH is required in the TCA cycle and further in the production of ATP, the energy currency of the cell. Aayushi Rambia Follow Post-graduate student from Pondicherry University, Department of Microbiology. Web15 okt. 2008 · Oxamate also inhibits aspartate aminotransferase (AAT), which functions in tandem with malate dehydrogenase to form the malate-aspartate NADH shuttle. AAT is required to shuttle electrons from glycolysis-derived cytoplasmic NADH to mitochondrial NADH, which are then used by the electron transport chain to generate a proton gradient …

Webcatalyzing enzyme: malate dehydrogenase, EC 1.1.1.37 (component of the malate aspartate shuttle) oxaloacetate + acetyl-CoA + H 2 O → citrate + CoASH; catalyzing enzyme: citrate synthase, EC 2.3.3.1 Reaction steps from malate to pyruvate and lactate. The conversion of malate to pyruvate and lactate is catalyzed by Web9 mrt. 2015 · The malate–aspartate shuttle is operated by two pairs of enzymes that localize to the mitochondria and cytoplasm, glutamate oxaloacetate transaminases (GOT), and malate dehydrogenases (MDH). Here, we show that mitochondrial GOT2 is acetylated and that deacetylation depends on mitochondrial SIRT3.
