Protein Processing, Post-Translational
| Medical Definition: |
Any of various enzymically catalyzed post-translational modifications of PEPTIDES or PROTEINS in the cell of origin. These modifications include carboxylation, HYDROXYLATION, ACETYLATION, PHOSPHORYLATION, METHYLATION, GLYCOSYLATION, ubiquitination, oxidation-reduction, degradation and lysis, peptide bond formation, and changes in molecular weight and electrophoretic motility. |

Protein Processing, Post-Translational Categories.
 |
Protein Isoprenylation - A post-translational modification of proteins by the attachment of an isoprenoid to the C-terminal cysteine residue. The isoprenoids used, farnesyl diphosphate or geranylgeranyl diphosphate, are derived from the same biochemical pathway that produces cholesterol. |
|
Protein Splicing - Excision of in-frame internal protein sequences (inteins) of a precursor protein, coupled with ligation of the flanking sequences (exteins). Protein splicing is an autocatalytic reaction and results in the production of two proteins from a single primary translation product: the intein and the mature protein. |
