FIGURE 2. Electron density maps of pyrithiamine
pyrophosphate and Mg^2+/AMP. A, omit 2F[o]-F[c] map of the bound
PPP molecule contoured at 1 S.D. of the map. In the upper panel,
a F[o]-F[c] map contoured at 3 S.D. shows the negative peak
surrounding the sulfur atom of TPP after replacing PPP with TPP
and performing a round of refinement in CNS. B, omit 2F[o]-F[c]
map of Mg^2+/AMP bound to TPK contoured at 1 S.D. of the map.
