Figure 5. Intersubunit Contacts(a) A closeup view of the
intermediate domain orientation in the unliganded T ring of
GroEL-ATP.(b) A similar view of the intermediate domain
orientation in the ATP-bound R ring. The equatorial (green),
intermediate (yellow), and apical (red) domains of parts of two
adjacent subunits are shown inside a blue/yellow wire mesh
surface representing the EM density. The change in color of the
mesh indicates the boundary between the two subunits in each
view. The T ring contains density at the E386-R197 salt bridge.
In the R ring, E386 makes a new contact near K80 and D83 in the
neighboring equatorial domain.
