Figure 3.
Fig. 3. Comparison of MtTS and TtTS active sites. Active-site residues of MtTS and the bound PLP are shown in gold, and equivalent residues of TtTS are in gray. Two important hydrogen bonds mentioned in the text are indicated by black dotted lines. Electron density is for the PLP in the last 2|F[o]| − |F[c]| map prior to its inclusion in the model, contoured at 1 σ = 0.2 e/Å^3.
