dc.description.abstract | Ovotransferrin (OT), a multifunctional glycoprotein with defensive and protective activities, accounts for approximately 13 % of chicken egg white proteins and is known as a major egg-associated allergen along with ovomucoid (OM). In contrast to the well-characterized N-glycans of OM, the N-glycan structure of OT has not been reported. Here, using HPLC equipped with a fluorescence detector and mass spectrometric analysis in combination with exoglycosidase digestion, we investigated the N-glycan type and branched pattern of OT, and compared them with those of OM. The HPLC peak area was used to calculate the relative quantity (%) of each glycan. Seventeen N-glycans, including 11 glycans (1 core structure and 10 complex-type oligosaccharides), that commonly exist in ovotransferrin and ovomucoid were identified. Six characteristic glycans (2 truncated structures, 1 complex-type, and 3 hybrid-type oligosaccharides) in OT and eight characteristic glycans in OM were classified. OT contains the following branched complex-type structures: mono-(13.2 %), bi-(23.9 %), tri-(9.0 %), tetra-(2.7 %), and penta-(2.8 %) antennary oligosaccharides. However, OM contained mostly tri-(33.5 %) and penta-(31.2 %) antennary oligosaccharides. The N-glycan-containing bisecting N-acetylglucosamine comprised 43.4 % and 79.8 % of the total glycans in OT and OM, respectively. Moreover, using circular dichroism analysis, we observed that the secondary structure of the deglycosylated OT is quite different from that of the intact protein. To our knowledge, this is the first study to analyze N-glycans in OT in comparison with those of OM. | - |
