Abstract: | In this study, we analyzed structural features of the N-glycans linked to glycoproteins expressed in various edible beans to identify excellent sources of useful N-glycans and N-glycopeptides. Structural analysis of N-glycans of the glycopeptides prepared from the pepsin digests of bean powder that the useful high-mannose type N-glycans occur predominantly in Phaseolus and Vigna beans; tora bean for Man?GlcNAc?-Asn, dainagon bean for Man?GlcNAc?-Asn, and azuki bean for Man?GlcNAc?-Asn. |
