post-translational proteic modifications

Sunday 30 November 2003

Post-translational modifications define the functional and structural plasticity of proteins in archaea, prokaryotes and eukaryotes.

Multi-site protein modification modulates protein activity and macromolecular interactions and is involved in a range of fundamental molecular processes.


- proteic glycosylation

  • O-linked N-acetylglucosamine (GlcNAc) glycosylation

- proteic methylation
- proteic acetylation
- proteic nitration
- proteic ubiquitylation
- proteic farnesylation
- proteic palmitoylation
- proteic phosphorylation (PO4)
- proteic transglutamination
- proteic prenylation
- proteic carboxyl methylation by methyltransferase
- endoproteolytic processing by protease
