CC -!- FUNCTION: The MdtABC tripartite complex confers resistance against
CC novobiocin and deoxycholate. {ECO:0000255|HAMAP-Rule:MF_01423}.
CC -!- SUBUNIT: Part of a tripartite efflux system composed of MdtA, MdtB and
CC MdtC. MdtB forms a heteromultimer with MdtC. {ECO:0000255|HAMAP-
CC Rule:MF_01423}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_01423}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_01423}.
CC -!- INDUCTION: The mdtABC operon is transcriptionally activated by BaeR.
CC -!- SIMILARITY: Belongs to the resistance-nodulation-cell division (RND)
CC (TC 2.A.6) family. MdtB subfamily. {ECO:0000255|HAMAP-Rule:MF_01423}.
