WebThe oxidative phosphorylation is the major pathway by which energy is obtained in the form of ATP using various fuels. Electron transport chain (ETC) is a series of enzyme complexes that organized in an order of decreasing reducing power. It is present on the inner mitochondrial membrane and is a major source of ATP synthesis in animal cells. WebThese modifications include phosphorylation, glycosylation, ubiquitination, nitrosylation, methylation, acetylation, lipidation and proteolysis and influence almost all aspects of normal cell biology and pathogenesis. Therefore, identifying and understanding PTMs is critical in the study of cell biology and disease treatment and prevention.
