CC -!- FUNCTION: The VirB system could be required for the establishment of
CC the replication niche in the host.
CC -!- INTERACTION:
CC Q7CEG3; Q9RPX5: virB10; NbExp=5; IntAct=EBI-6407073, EBI-7022388;
CC Q7CEG3; Q7CEG3: virB8; NbExp=6; IntAct=EBI-6407073, EBI-6407073;
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Single-pass
CC membrane protein {ECO:0000305}.
CC -!- INDUCTION: Specifically induced within macrophages by phagosome
CC acidification. Induced at 37 degrees Celsius in minimal medium,
CC suggesting that nutritional stress is a regulating signal.
CC -!- MISCELLANEOUS: Transcription of the operon is maximal in early
CC exponential phase.
CC -!- SIMILARITY: Belongs to the virB8 family. {ECO:0000305}.
