Figure 2. Architecture of MukBEF.
(A) Organization of MukBEF and MksBEF. ATP-mediated dimerization of MukB head creates a high affinity DNA binding site. The head can accommodate a single C-terminal WHD of MukF. N-terminal WHD of MukF is prone to further dimerization. With the exception of the shorter coiled coils, MksBEF is predicted to form a similar structure to MukBEF.
(B) A possible organization of MukBEF if dimerization interfaces of its hinge and head domains face away from each other.
