Involved in resistance to several unrelated toxic compounds, such as dyes, detergents and antibiotics. Probably part of a tripartite efflux pump, which is composed of an outer membrane efflux protein, an inner membrane protein and a protein that expands the periplasmic space. Could form a tripartite pump with BepC and BepD. Repressed by BepR. Shows increased sensitivity to deoxycholate, ethidium bromide and crystal violet. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
