Figure 1

Least-squares superposition of the two subunits of CRPMt (3H3U), and CRPMt (3H3U) and CRPMt (3D0S). The RMSD values for the superposition (see text for details) using all of the residues (A) is considerably higher than those obtained using the coordinates of only the cAMP-binding domain (Fig. S1) or the DNA-binding domain (Fig. S1), reflecting the fact that the two domains are oriented differently in the two subunits. Within the DNA-binding domain, apart from the reorientation of the D-helix, the rest of the domain shows good structural alignment. (B) Superposition of the B-chain of CRPMt (3H3U) and CRPMt (3D0S).
