Glycopeptides of moss-produced rhEPO from two glyco-engineered moss lines. Comparison of the mass spectra for the rhEPO tryptic peptide harboring two glycosylation sites (EAENITTGCAEHCSLNENITVPDTK) produced in glyco-engineered moss lines: double KO ΔXylT/FucT and triple KO ΔXylT/FucT/GalT (based on Parsons et al., 2012). Salt adducts are marked with asterisks. The glycosylation patterns are schematized with sugar symbols above each peak. Lea structures are totally absent in the triple KO line.
