ET_eff values corresponding to the mean energy transfer efficiency obtained from histograms as described in the Materials and Methods (n = 4 for all constructs except for αS LF pH 7.4 where n = 3); error is standard deviation of the mean. Significance level of βS or γS ET_eff values relative to αS (*); significance level in ET_eff for each protein at pH 3.5 relative to pH 7.4 (+). */+ indicates results that are significant at the 5% level using a two-tailed Mann-Whitney U-test. AH–amphipathic helix motif-containing construct; LF–flexible loop forming construct; NAC–non-amyloid beta component or hydrophobic core construct; CT–C-terminal construct.
