posttranslational modifications

posttranslational modifications

processes occurring after TRANSLATION of a POLYPEPTIDE, that are often needed to generate a fully functional polypeptide. Modifications include the introduction of a new functional group, specific PROTEOLYSIS, GLYCOSYLATION, protein phosphorylation (see PROTEIN KINASE) and METHYLATION.
