Post-translational chemical modification(s) of proteins

1. The role played by the modification of protein in determining its fate is reported by us. 2. Post-translational modifications such as acetylation, phosphorylation, sulfation, methylation, hydroxylation, ADP-ribosylation, maturation, amidation, carboxylation, adenylylation, glycosylation, ubiquitination, and prenylation are extensively reviewed. 3. Each post-translational modification's significance and its role played in biological function(s) is summarized in the general discussion and the conclusion's remark is directed at the problems left to solve (e.g. post-translational modification reactions in recombinant protein in modern genetic engineering).
