Figure 4.
Probability distribution of the RMSD values with respect to the two representative conformations for cluster 1 (a) and cluster 2 (b), identified from cluster analysis of the antibody/de-acetylated saccharide system. The distributions were derived from simulations of the antibody/de-acetylated saccharide (solid black), antibody/O-acetylated saccharide (solid red), unbound de-acetylated (black dotted) and O-acetylated (red dotted) saccharides. The RMSD values were computed for all pyranose ring non-hydrogen atoms after alignment to the central tetrasaccharide unit.
