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.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000255|PROSITE-ProRule:PRU00441}.
CC -!- SIMILARITY: Belongs to the binding-protein-dependent transport system
CC permease family. OppBC subfamily. {ECO:0000305}.
