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}.
