^aExcept as noted, sedimentation equilibrium data are for 200 μM peptide solutions in 10 mM aqueous sodium acetate, pH 4.6 + 150 mM NaCl, at 25 °C. Data for 1 and 2 are from reference ⁴⁸ and are included for comparison.

^bSee Supporting Information for details. A single number indicates that the best-fit model was for a single species of the following size: 1=monomer, 2=dimer, 3=trimer, etc. Multipe numbers in parentheses indicate that the best-fit model is for multiple species in equilibrium: (1,4,5) indicates a monomer-tetramer-pentamer equilibrium.

^cData for 3 were collected at 100 μM peptide and in 10 mM sodium acetate, pH 4.6 (no NaCl).
