| + | Periplasmic adaptor proteins are key components of bacterial tripartite efflux pumps. The 2.85A resolution structure of an MFS (major facilitator superfamily) pump adaptor, Aquifex aeolicus EmrA, shows linearly arranged alpha-helical coiled-coil, lipoyl, and beta-barrel domains, but lacks the fourth membrane-proximal domain shown in other pumps to interact with the inner membrane transporter. The adaptor alpha-hairpin, which binds outer membrane TolC, is exceptionally long at 127A, and the beta-barrel contains a conserved disordered loop. The structure extends the view of adaptors as flexible, modular components that mediate diverse pump assembly, and suggests that in MFS tripartite pumps a hexamer of adaptors could provide a periplasmic seal. | ||
