Fig. 3. Comparison of the monovalent ion-binding site of
BCK, MutL, GyrB, human Hsp90 and CheA. Secondary structures
surrounding the ATP-binding site are shown in gray ribbon
drawings including motifs I (N) and IV; motif II (G1) and the N-
and C-terminal (motif III) hinges of ATP lid are drawn in
yellow. For clarity, the connecting part of the ATP lid is not
shown. The bound nucleotides are shown in ball-and-stick models,
divalent and monovalent cations are shown as cyan and purple
spheres, and water oxygens as red sphere.
