Fig. 3. Structure at the CR2-C3d interface. (A and B) Surface
features of the interface area on C3d (in cyan) and CR2 molecule
(in yellow). The shape of the interface of one molecule
complements that of the other (prepared using GRASP). (C)
Structure of the CR2 SCR2 (yellow) and C3d (cyan) complex. (D
and E) The detailed interactions between CR2 (yellow) and C3d
(cyan) in two angles. Dashed lines represent H-bonds between
carbonyl oxygen atoms (red), nitrogen atoms (blue) of amino acid
side chains or main chain, and water molecules (pink).
