Figure 2
Preliminary structure of NovR. Ribbon representations showing (a) top and (b) side views of the model built by ARP/wARP with individual subunits shown in different colours. The red spheres indicate putative nickel sites found by inspection of an anomalous difference Fourier map, which correspond to the zinc sites of the template aldolase structure. (c) Stereographic projection showing overlaid (not least-squares superposed) Cα traces of single subunits from the molecular-replacement solution (yellow) and the ARP/wARP model (blue). This corresponds to the blue subunit depicted in (a) and (b) and has the same orientation as that shown in (b). Note in particular the additional structure at the N- and C-termini of the ARP/wARP model and the significant shifts in some of the secondary-structural elements. The red spheres show the two metal ions associated with this subunit. Figures were generated using PyMOL (DeLano, 2002  ). |
