The malate-aspartate shuttle
Splet25. nov. 2014 · From this perspective, an intracellular lactate shuttle operates much like the malate-aspartate shuttle; it is also proposed that the two shuttles are necessarily interconnected. Among the requisite features of such a model, significant compartmentalization of LDH, much like the creatine kinase of the PCr shuttle, would … SpletCitrin is aspartate/glutamate transporter in mitochondria, a component of malate-aspartate nicotinamide adenine dinucleotide hydrogen shuttle, and is essential for the hepatic glycolysis. Although the precise pathophysiology of citrin deficiency remains unclear, recent reports for the effective MCT supplement therapy and downregulation of ...

SpletMalate-Aspartate Shuttle Pathway (Concept Id: C1518158) The process of transferring reducing equivalents from the cytosol into the mitochondria; NADH is used to … SpletThe mdh1Δaat1Δ double mutation blocks CR-mediated life span extension and also prevents the characteristic decrease in the NADH levels in the cytosolic/nuclear pool, suggesting that the malate–aspartate shuttle plays a major role in the activation of the downstream targets of CR such as Sir2. Overexpression of the NADH shuttles may also ...
SpletThe malate shuttle allows the mitochondria to move electrons from NADH without the consumption of metabolites and it uses two antiporters to transport metabolites and keep balance within the mitochondrial matrix and cytoplasm . SpletClinical symptoms can be traced back to disruption of the malate-aspartate shuttle due to the lack of citrin. A potential therapy for this condition is the expression of aralar, the AGC …
Splet23. feb. 2011 · In the heart, the malate–aspartate shuttle (MAS) constitutes the primary metabolic pathway for transfer of reducing equivalents from the cytosol into the mitochondria for oxidation. The flux of MAS is tightly linked to the flux of the tricarboxylic acid cycle and the electron transport chain, partly by the amino acid l -glutamate.
