Figure 2
A stereoimage showing six monomers of CGL (A–F, the content of the asymmetric unit) in ribbon representation, together with the 2Fo − Fc electron-density maps covering residues 50–70 in each of the monomers. The electron-density maps are contoured at the 1.3σ level. (a) Maps were calculated with the best phases obtained from the molecular replacement. Notice a lack of interpretable electron-density peaks in the regions of monomers E and F. (b) Maps were calculated using the phases corresponding to the final refined model of CGL. |
