Figure 2
(a) The omit Fo − Fc difference density observed for UDP-FGal binding in the subunit A active site of TbGalE. The map, depicted as a purple mesh, is contoured at 2σ. The ligand is shown as a stick model with atomic positions coloured according to type: C, grey; N, blue; O, red; P, purple; F, green. This is the ligand orientation that will be used in all figures. Figs. 2–5 were prepared with PyMOL (DeLano, 2002). |
