CC   -!- FUNCTION: Part of the binding-protein-dependent transport system for
CC       oligopeptides; probably responsible for the translocation of the
CC       substrate across the membrane. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC       membrane protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC   -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC       permease family. OppBC subfamily. {ECO:0000305}.
