• Holm, Anders; Rise, Frode; Sessler, Nicole; Sollid, Ludvig Magne; Undheim, Kjell & Fleckenstein, Burkhard (2007). Specific Modification and Subsequent Mass Spectrometric Detection of Citrulline Containing Peptides. Vis sammendrag

  The posttranslational deimination of polypeptide-bound arginine residues is known as citrullination and is catalyzed by a family of Ca2+ dependent enzymes called peptidylarginine deiminases. Immune reactions to such citrulline containing proteins appear to be central in the immunopathogenesis of rheumatoid arthritis. Consequently there is a need to characterize which proteins in the inflamed joints of rheumatoid patients contain citrulline residues in situ. As demonstrated for a series of other posttranslational modifications, such as phosphorylation and glycosylation, the characterization of citrullinated proteins and peptides in complex mixtures is greatly facilitated by techniques allowing their specific enrichment and/or detection. So far such methods are not available for citrullinated peptides. As a first step towards the directed analysis of citrullinated proteins and peptides in rheumatoid arthritis, this study presents a method for the specific modification of peptide bound citrulline residues. This chemical reaction uses 2,3-butanedione and antipyrine as modifying reagents and is performed in 25-50 % TFA at 37°C. The modification shifts the mass of citrullinated peptides by 238 Da. NMR was applied to elucidate the structure of the modification product using N-butylurea as a model compound. Modified citrulline residues absorb at 464 nm enabling their selective detection and fractionation in liquid chromatography (LC). In order to verify the chemical structure of the modification and to investigate the generation of modification-specific fragment ions, modified citrulline containing peptides were subjected to collision induced dissociation experiments. Two fragments ions characteristic for modified citrulline residues were detected and will be presented. The usefulness of these signature ions to specifically detect modified citrullinated peptides in heterogeneous mixtures by nano LC-MS/MS will be discussed. Analysis was performed on ESI-ion trap, ESI-q-TOF and MALDI-TOF/TOF mass spectrometers.
