Figure 1

Quasirigid domain displacement: (A) Open crystal structure. The centers of mass of the OB domain (the noncatalytic-accessory domain), colored in red, and the nucleotidyltransferase domain (the catalytic domain), colored in blue, are separated by 30.3 Å. The hinge region is colored in yellow, and GTP is rendered in licorice and colored by atom type. (B) Closed crystal structure, coloring is as in (A). The centers of mass of the OB and nucleotidyltransferase domains are separated by 25.5 Å.
