F the biochemical hallmark of NETs is citrullination of histone proteins [39-41]. This modification is made up of a deimination of arginine residues, carried out by protein-arginine deiminases (PAD1-PAD4), that sales opportunities to the change of 0.985 Da in molecular mass. An extremely stringent bioinformatic and exact handbook examination of all peptide fragmentation spectra, demanded for warranting attribution of this modification, enabled to detect a complete of four peptides carrying the arginine PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/22920093 to citrulline modification, belonging to histones H1.4, H2A and H2B, as demonstrated in Desk four. Figure 4 experiences a consultant fragmentation spectrum, relative for the citrullinated peptide SSR*AGLQFPVGR (other citrullinated peptide spectra are reported in Extra file five). These peptides demonstrate a spine composed by cleavage items of b and y ions and several other neutral loss ions, at the same time given that the decline of ammonia (-17 Da) and h2o (-18 Da) close to the precursor ion. While in the y ion sequence all products and solutions that bring on modified arginine residue is usually found, highlighting that the presence of this residue disadvantages ionization of subsequent fragments, due to loss of Reveromycin A favourable charge linked with citrullination [42] (Figure three).Pisanu et al.
