Fig. 4.
Top left: The linker portion of TF-Sp8 (stick, goldenrod atom coloring) is tolerated in the binding site of the glycan-binding protein, JAA-F11 (surface, cyan). Top right: The linker portion of TF-Sp16 is not tolerated in the binding site of JAA-F11 (surface, cyan) due to overlaps with the side-chain of Tyr 34 (surface, transparent cyan). Bottom left: The linker portion of Sp8-TF (stick, goldenrod atom coloring) presents the TF-antigen relative to the array surface (disc, dark gray) so that JAA-F11 (surface, cyan) is able to bind. Bottom-right: The linker portion of Sp14-TF (stick, goldenrod atom coloring) presents the TF-antigen relative to the array surface (disc, dark gray) so that JAA-F11 (surface, cyan) is unable to access the glycan.
