Lysine Modifications & Arginine Modifications

Arginine Modifications

Frequently occurring post-translational arginine modifications are the transformation to citrulline and the nitration to nitro-arginine.

Lysine Modifications

Typical post-translational lysine modifications are succinylation, malonylation, lactoylation and acylation including propionylation and acetylation.  Another modified lysine (Lys(GG)) is formed by the tryptic digestion of ubiquitinylated peptides. The resulting peptide is a valuable reference standard for the determination of ubiquitinylation via proteomics workflows.
