Theoretical model of the NlaIV dimer complexed to the target DNA, based on the homologous EcoRV structure. Backbones of both monomers are shown as gold ribbons. The active sites are indicated by the presence of metal ions (red spheres), whose coordinates were copied from the template. For detail, see Chmiel et al., pages 181–189. The art work was created with PyMol by Jan Kosinski (IIMCB, Warsaw).
