From: The transcriptional regulator GalR self-assembles to form highly regular tubular structures
(A) CD spectra of 3.8 μM GalR diluted in buffers containing different [NaCl]. The label “150–500 mM” denotes an initial 1 h incubation with 150 mM NaCl after which the concentration was raised to 500 mM and incubated for an additional hour before this spectrum was recorded. (B) CD spectra of 3.8 μM GalRWT at different [NaCl] and 10 mM D-galactose added either before (bef) or 1 hour after (aft) the protein was introduced. Spectra recorded in the absence of D-galactose at 250–1000 mM (ref) are included.
