About 50 protein fractions with molecular mass 15-158 kDa were detected in purified mitochondria isolated from rat liver homogenate after two-dimensional electrophoresis performed as described by O'Farrell. Individual spots, corresponding to proteins of inner mitochondrial membrane, disappeared from electrophoregrams as a result of incubation of the isolated mitochondria at 37 degrees and pH 7.5. Degradation of these proteins was augmented if ATP was added into incubation mixtures. Intrinsic proteolytic activity occurred in rat liver mitochondria as shown by these and previously obtained data.

UI MeSH Term Description Entries
D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.
