After verifying good diffraction by these crystals, some were transferred to a drop of mother liquor supplemented with glycerol and ~0.2 mM ZnCl2. After 1 week this crystal was flash-cooled for data collection. During analysis of Zn binding presence of the inhibitor was overlooked, and in the primary citation publication the anomalous signal of I in the inhibitor was mistakenly attributed to a second Zn binding site, Zn02.

After verifying good diffraction by these crystals, some were transferred to a drop of mother liquor supplemented with glycerol and ~0.2 mM ZnCl2. After 1 week this crystal was flash-cooled for data collection. During analysis of Zn binding presence of the inhibitor was overlooked, and in the primary citation publication the anomalous signal of I in the inhibitor was mistakenly attributed to a second Zn binding site, Zn02.
