In <scene name='69/694218/Mutationh260q/1'>Ag85C-H260Q</scene> (Figure 10), a shift in helix α-9 prevents the formation of any stabilizing hydrogen bonds between residues His260 and Glu228, thus decreasing its enzymatic activity (Figure 11).  The conversion of the glutamate, a key player in the catalytic triad, to the corresponding amide-containing side chain as well as a loss of a general base in the charge relay are both key causes for the loss of function.<ref name="Favrot"/>
