Type: | Domain | Name: | Multidrug efflux transporter AcrB TolC docking domain, DN/DC subdomains |
Description: | The multidrug exporter AcrB is the inner membrane component of the AcrAB-TolC drug efflux system in Escherichia coli, responsible for the resistance of this organism to a wide range of drugs. AcrB exists as a homotrimer, with each subunit containing 12 transmembrane (TM) helices and a large periplasmic part formed by two loops between TM helices 1 and 2 and TM helices 7 and 8. The trimer consists of three prominent domains, the TM domain, the adjacent pore domain and the TolC docking domain []. This entry represents two subdomains, known as DN and DC, found in the TolC docking domain of multidrug resistance proteins like AcrB []. | Short Name: | AcrB_DN_DC_subdom |
