Figure 1. Detergent-associated MakA trimer of dimers.

a) Cryo-EM map of the MakA trimer of dimers fitted with the atomic model. The head and tail regions are labeled, and the angle between one dimer and the C3 symmetry axis is indicated. b) Zoomed-in view of the transmembrane region. Chains A and B, which form the same asymmetric dimer, exhibit slightly different degrees of insertion into the detergent micelle. c) Rotated view of the MakA trimer of dimers. d) Interaction between two adjacent dimers through chains A and chain F. e) Surface electrostatic potential of the MakA trimer of dimers.
