Fig. 4.
Docking of a glycan chain fragment into the groove of MotB-C accommodating NAM. (A) Stereoview illustrating the interactions between the docked nine-residue (NAM-NAG) fragment, shown in black lines, and protein loops Asp-165–Tyr-177 (drawn with carbons in brown) and Ser-208–Asp-216 (drawn with carbons in cyan) of the MotB-C monomer. (B) Stereo drawing showing the direction of the peptide stems (yellow arrows) attached to the (0) and (+2) NAM residues of the glycan chain, with respect to the molecular surface of MotB-C. The side chains of Arg-172, Thr-209, Asp-165, and Arg-221 are shown in red in a ball and stick representation.
