Post translational modifications can be defined as:
In other cases such chemical alterations have changed the protein function entirely. Posttranslational modification (ptm) of proteins, being one of the later stages in protein biosynthesis, refers to the reversible or irreversible chemical changes proteins may undergo after translation. Can involve very complex systems of enzymes. Consequences on the structure and functions of the protein modified. Over the past 20 years, mass spectrometric analysis has become an essential tool in determining the types and sites of protein modifications. The term protein is derived from a greek word proteios, meaning first place. Cannot be definitively predicted from dna sequence. B chemical modification of histidines. Chemical modifications, protein activity, and longevity. More than 200 diverse types of ptms are currently known (5,6), ranging from small chemical modifications (e.g., phosphorylation and acetylation) to the addition of complete proteins (e.g., ubiquitylation, figure 3).
