MS/MS spectrum of the tryptic peptide. (A) The tryptic peptide TLTGK*TITLEVEPSDTIENVK from epididymis luminal protein 112 (B2RDW1) or ubiquitin-40S ribosomal protein S27a (P62979). (B) The tryptic peptide ADALQAGASQFETSAAKLK* from uncharacterized protein (L7N2F9). (C) The tryptic peptide K*VLGAFSDGLAHLDNLK from hemoglobin subunit beta (P68871) or beta-globin (D9YZU5). The observed b- and y-ions were labeled in each MS/MS spectrum. K* = ubiquitinated lysine residue.
