Figure 8

The variant C674R. Panels (A and B) respectively show the N eq and the ΔPB curves of the C674 (WT) and R674 (variant) systems. Panel C show the PB maps of residues 669 to 676 for the WT (above) and the variant forms (below). (D) Molecular interactions made by the residues C674 or R674 and (E) R671. For colour scales and residue presentation, see the legend of Fig. 6.
