Abstract

The degree of compaction inferred from SAXS experiments by Riback et al. for unfolded proteins in water versus chemical denaturant is highly consistent with the results from FRET experiments. There is thus no “contradiction” between the two methods, nor evidence to support their claim that commonly used FRET fluorophores cause protein compaction.
