Figure 6
Crystal structure model of a putative glutaminase from G. kaustophilus (a). The dashed circle indicates the region of the deposited model shown in (b) with the corresponding maps. A deletion near Val B/57 results in multiple strong positive difference-density map peaks and a register shift in the fragment shown in red in (a). The panel depicts residues 56–59 from chain B (red) and superposed models of the remaining chains A, C and D (grey). After correcting the model and subsequent restrained refinement the map–model agreement clearly improves (c). The combined 2mFo − DFc (blue) and difference mFo − DFc (red/green) maximum-likelihood maps calculated using REFMAC5 and PDB-REDO are shown at 2σ and 3σ levels, respectively. |
