Ribbon diagrams of the β-trefoil lectin domains of O. sativa EULs. a-h. Ribbon diagrams of the separate EUL domains of OsEULS2 (a), OsEULS3 (b), OsEULD1A_1 (c), OsEULD1A_2 (d), OsEULD1B_1 (e), OsEULD1B_2 (f), OsEULD2_1 (g), and OsEULD2_2 (h). Beta-sheets, stretches of α-helices and loops are colored magenta, orange and green, respectively. The bundles of β-sheet are numbered I, II and III, respectively. The carbohydrate-binding site of the EUL domain is located at the bundle III. i-j. Ribbon structure of the two-β-trefoil domain OsEULD1A (i) and OsEULD1B (j), showing the respective arrangement of the two β-trefoil domains on both sides of the central linker region (L). The arrow indicates the carbohydrate-binding site in subdomain III. N and C correspond to the N- and C-terminal ends of the polypeptide chain of OsEULD1A and OsEULD1B, respectively
