(A) Light scattering of 2 μM GalR^WT (black) and GalR^N48I (grey) after dilution in a buffer containing a final concentration of 150 mM NaCl. (B) NS-TEM images of aggregates formed after dilution of GalR^N48I in a buffer containing 150 mM NaCl. The initial ordered structures could be observed, but, unlike in the case of GalR^WT (Fig. 8A), the highly ordered polymers did not emerge from these structures.
