CC   -!- FUNCTION: The VirB system could be required for the establishment of
CC       the replication niche in the host.
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 TrbG/VirB9 family. {ECO:0000305}.
