Fig. 3

Wildtype S100A5 is prone to the formation of high-ordered oligomers. Sedimentation velocity AUC distribution plots showing (a) apo wildtype S100A5, (b) wildtype S100A5 saturated with Cu2+ and Ca2+, (c) apo Cys-Ser double mutant, and (d) Cys-Ser double mutant saturated with Cu2+ and Ca2+. Data are normalized to the same scale. Homodimers are the peaks near s=2. The Cys-Ser double mutant plots show evidence of some monomer (peak near s=1) in solution
