Figure 6.

Percent occupancies of aliphatic interactions between C3d and FH at (A) binding site 1, (B) binding site 2, and (C) binding site 3. These values represent the percentage of snapshots throughout the triplicate trajectories for each binding site where a pair of functional groups with aliphatic features were observed to be within 4 Å in the C3d:FH complex. Residue labels are colored according to secondary structure. Black represents a coil or turn; red represents an α-helix; blue represents a 3₁₀-helix; green represents a β-sheet; and magenta represents an isolated β-bridge.
