Fig. 3. Structure of the complex between DnaB and HBD. (A)
(Top) "Top" view of a ribbon representation of the complex
showing the three HBDs (green) bound at the periphery of the NTD
collar (light blue and blue). The CTD and linker region are
colored red and yellow, respectively. (Bottom) The interface
between DnaB and HBD shown as ribbons with a transparent
surface. (B) "Side" view of a surface representation of the
complex revealing no interaction between the HBDs (green) and
the DnaB CTD (red) or linker region (yellow). (C) Backbone trace
of the HBD DnaB interface, residues known to modulate the
interaction between DnaB and DnaG, are shown as colored spheres.
