Outline of Final Research Achievements

The presence of branched structures is a characteristic of glycans, rarely found in other biomolecules such as proteins or nucleic acids. To understand the biological significance of arm-specific carbohydrate recognition by lectins, it is a prerequisite to evaluate interactions with the asymmetric branched glycans. In this study, we focused on the asymmetry of each glycan branch and analyzed in detail the structure, dynamics and interaction based on experimental (NMR, ion mobility spectrometry) and theoretical (molecular dynamics simulation) approaches. We revealed the structural basis of branch asymmetry and its role in lectin recognition.
