tAlong with the traditional yeast Saccharomyces cerevisiae, nonconventional yeast species are becoming increasingly attractive hosts for the secretory production of recombinant proteins. Glycosylations of secretory proteins in yeast species occur on asparagine (N) and/or serine/threonine (O) residues through the secretory pathway. The establishment of methods to assess the degree and size of N- or O-glycosylation is particularly useful in the development of expression systems for therapeutic proteins. Whereas the structure of N-linked oligosaccharides of various yeast species have been well characterized1,2, the structural analysis of yeast O-linked oligosaccharides has been hampered due to lack of a universal method to release O-glycans enzymatically. Here, we tried to define O-linked glycan profiling of cell wall mannoproteins and secretory protein chitinase derived from the two nonconventional yeast species, the methylotrophic yeast Hansenula polymorpha and dimorphic yeast Yarrowia lipolytica, based on the ‘ammonia-based β-elimination’ method. The released O-linked oligosaccharides were effectively isolated, labeled with fluorescence tags, and then analyzed using HPLC and CE-based DNA sequencer. The results of α-mannosidase treatment experiment showed that the O-linked glycans from both yeasts, H. polymorpha and Y. lipolytica, are mainly composed of two to five α-mannoses.
