Figure 6.
Structural FosB/JunD assembly reveals a binding pocket. A dimer-of-dimers is generated by crystallographic symmetry (CS) or non-crystallographic symmetry (NCS) as exemplified by the FJ and FJoxi (type I) structures. CS and NCS operations are shown as red and green arrows, respectively. Side view of FJoxi indicates the location of a pocket; zoomed-in views show the pocket (top right) and its electrostatic surface contour (bottom right). Chloride ions found in the pocket are shown as green spheres and the electron density for these atoms is included (2mFo – DFc map contoured at 1.0σ).
