Figure 2
Electron density for the TTQ site of MauG-TTQOQ MADH in space groups P21 (a) and C2 (b) and MauG-TTQOX MADH (c). Atoms are shown in stick form colored according to element and 2Fo - Fc density contoured at 1.0[sigma] is shown as a blue mesh. (d) Comparison of hydrogen-bonding interactions to TTQ in MauG-TTQOQ MADH in space groups P21 (yellow) and C2 (cyan) and MauG-TTQOX MADH (magenta). Water molecules are shown as spheres coloured as for the C atoms. This figure was produced using PyMOL (http://www.pymol.org/ ).  [article HTML]
