Improved structure of the isochorismate synthase MenF. (a) Stereoview of the MenF monomer colored from blue (N-terminus) to red (C-terminus). The magnesium ion found in the active site is shown in blue, along with two water molecules and a sulfate ion. (b) Magnesium coordination in the active site of MenF. The positive difference density calculated after omitting Glu284, Glu416, the sulfate ion, Mg2+ and its associated two O atoms from a round of refinement with REFMAC5 (Murshudov et al., 1997BB10) is contoured at 4σ and shown with the refined model.
