Figure 5
Overlay diagram of MexBYB-Ka-supplemented II and MexY protomers. (a, b, c) Protomers A, B and C of MexBYB-Ka-supplemented II (green) fitted on protomers A, B and C of MexY (EMDB entry EMD-10371; gray) by aligning PC2. (d, e, f) Protomers A, B and C of MexBYB-Ka-supplemented II (green) fitted on protomers A, B and C of MexY (EMDB entry EMD-10371; gray) by aligning PN1. The side view of the protomer and the top view of the porter domain are shown and significant changes are indicated by a dashed circle in red.
