Here our data showed that the malate–aspartate shuttle played a major role in mediating life span extension under CR as well as in Figure 6. " - The malate–aspartate shuttle

The malate–aspartate shuttle

SpletThis pathway is known as the malate-aspartate shuttle, because it involves exchange of mitochondrial aspartate for cytosolic malate: aspartate from the mitochondria crosses to the cytosol. aspartate is transaminated (at the expense of ketoglutarate) to yield oxaloacetate oxaloacetate is reduced to malate by cytosolic NADH SpletThe two main systems in humans are the glycerol phosphate shuttle and the malate-aspartate shuttle. The malate / a-ketoglutarate antiporter functions move electrons while the aspartate / glutamate antiporter moves amino groups. This allows the mitochondria to receive the substrates that it needs for its functionality in an efficient manner. [1]
