Figure 2.
Figure 2 (A) Stereo view of one of the ATP-binding sites in the
HlyB-NBD H662A dimer. ATP is shown in stick representation, Mg2+
as a green sphere, and water molecules as blue spheres. (B)
Schematic diagram of the interactions between one of the two
ATP/Mg2+ complexes and HlyB-NBD H662A. (C) Schematic diagram of
the interactions across the monomer -monomer interface. Color
coding is identical to Figure 1. Residues involved in monomer
-monomer contact are highlighted by gray boxes, while residues
involved in protein -ATP contacts are colored in boxes according
to Figure 1. Blue numbers indicate water molecules. Hydrogen
bonds and salt bridges are shown as solid lines, while van der
Waals and hydrophobic interactions are shown as dashed lines.
Letters represent the atoms involved in the interaction.
