Abstract:
Pyruvate occupies a central role in energy homoeostasis, and dysregulation of its cellular disposition underlies many metabolic disturbances. Although the mitochondrial membrane pyruvate transporter has been characterized, its molecular identity has proved elusive. Recent work has now identified a single candidate protein for the mitochondrial pyruvate carrier in yeast, opening the way for further studies in mammalian systems, which may have important therapeutic applications within the context of metabolic disease.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
