AcrAB fusion protein was generated by fusing functional AcrA dimer to the C-terminus of AcrB with a short transmembrane linker, and MacA-TolC alpha hybrid dimer was bound to the fusion protein in order to generate the complete tripartite complex

Particles were manually selected and boxed in 256 x 256 pixel boxes using e2boxer.py. Boxed particles were used to estimate and correct for CTF using e2ctf.py. Initial model from selected class averages was generated using e2initialmodel.py, and the 3D refinement was performed using e2refine_easy.py.
