Figure 4: Stereo views of conformational changes observed in the
quaternary complex. a, A comparison between the quaternary
complex (blue) and the HutP -HBN complex (red) showing the
structural differences around the l-histidine and Mg2+ binding
site. Symm. related mol., neighbouring dimer within the hexamer.
b, Conformational changes observed in the loop L3 region,
coloured as in a. c, Conformational changes observed in loop L5,
coloured as in a.
