Mechanism of protein biosynthesis in mammalian mitochondria

Mechanism and Regulation of Protein Synthesis in Mammalian Mitochondria

Abstract The mammalian mitochondrial translation machinery is responsible for the synthesis of 13 mitochondrially encoded proteins that are essential for energy production. These proteins are subunits of the oxidative phosphorylation complexes embedded in the inner membrane of mitochondria. Mitochondrial protein synthesis is highly similar to that of bacterial systems; however, there are subtle...

Prediction of Protein Sub-Mitochondria Locations Using Protein Interaction Networks

Background: Prediction of the protein localization is among the most important issues in the bioinformatics that is used for the prediction of the proteins in the cells and organelles such as mitochondria. In this study, several machine learning algorithms are applied for the prediction of the intracellular protein locations. These algorithms use the features extracted from pro...

Identification of a de novo thymidylate biosynthesis pathway in mammalian mitochondria.

The de novo and salvage dTTP pathways are essential for maintaining cellular dTTP pools to ensure the faithful replication of both mitochondrial and nuclear DNA. Disregulation of dTTP pools results in mitochondrial dysfunction and nuclear genome instability due to an increase in uracil misincorporation. In this study, we identified a de novo dTMP synthesis pathway in mammalian mitochondria. Mit...
