CC   -!- FUNCTION: Outer membrane channel, which is required for the
CC       function of several efflux systems such as AcrAB-TolC, AcrEF-TolC,
CC       EmrAB-TolC and MacAB-TolC. These systems are involved in export of
CC       antibiotics and other toxic compounds from the cell. TolC is also
CC       involved in import of colicin E1 into the cells.

CC   -!- SUBUNIT: Homotrimer. Part of tripartite efflux systems, which are
CC       composed of an inner membrane transporter, a periplasmic membrane
CC       fusion protein, and an outer membrane component, TolC. The
CC       complexes form a large protein conduit and can translocate
CC       molecules across both the inner and outer membranes. TolC
CC       interacts with the membrane fusion proteins AcrA, EmrA and MacA.

CC   -!- DOMAIN: Forms a continuous, solvent-accessible conduit: a
CC       'channel-tunnel' over 140 Angstroms long that spans both the outer
CC       membrane and periplasmic space. The periplasmic or proximal end of
CC       the tunnel is sealed by sets of coiled helices.
