Oxidative Post-translational Modification of Tryptophan Residues in Cardiac Mitochondrial Proteins

Post-translational oxidative modification and inactivation of mitochondrial complex I in epileptogenesis.

Mitochondrial oxidative stress and damage have been implicated in the etiology of temporal lobe epilepsy, but whether or not they have a functional impact on mitochondrial processes during epilepsy development (epileptogenesis) is unknown. One consequence of increased steady-state mitochondrial reactive oxygen species levels is protein post-translational modification (PTM). We hypothesize that ...

Computational Prediction of Post-Translational Modification Sites in Proteins

The last several decades have witnessed rapid progresses in identification and functional analysis of post-translational modifications (PTMs) in proteins. Through temporal and spatial modification of proteins by covalent attachment of additional chemical groups and other small proteins, proteolytic cleavage or intein splicing, PTMs greatly expand the proteome diversity and play important roles ...

Post-Translational Modifications of Cardiac Mitochondrial Proteins in Cardiovascular Disease: Not Lost in Translation

Protein post-translational modifications (PTMs) are crucial in regulating cellular biology by playing key roles in processes such as the rapid on and off switching of signaling network and the regulation of enzymatic activities without affecting gene expressions. PTMs lead to conformational changes in the tertiary structure of protein and resultant regulation of protein function such as activat...

Post-translational modification of PII signal transduction proteins

The PII proteins constitute one of the most widely distributed families of signal transduction proteins in nature. They are pivotal players in the control of nitrogen metabolism in bacteria and archaea, and are also found in the plastids of plants. Quite remarkably PII proteins control the activities of a diverse range of enzymes, transcription factors and membrane transport proteins, and in al...
