I. Introduction
Post-translational modifications, abbreviated as PTMs, are the alternation of protein after the formation of protein in the process of Central Dogma. Normally these modifications or alternations occur on the side chain of specific protein units called as amino acids. For example, Lysine residue is responsible for Glycation PTM. PTMs can be several types. For example, hydroxylation, carbonylation, nitration, glycation and so on. These PTMs are responsible for the diversity of protein in terms of their functions and structures additionally, the plasticity of active cells are greatly influenced by these alternations [1]. Expansion of genetic code and regulation of physiology of the living cells are the results of PTMs [2], [3].
