CC -!- FUNCTION: Component of the type III secretion system, which is required
CC for effector protein delivery, parasitism, and pathogenicity. Probably
CC participates in the formation of a C-ring-like assembly along with
CC HrcQa (By similarity). {ECO:0000250, ECO:0000269|PubMed:12580281}.
CC -!- SUBUNIT: Homotetramer. The four monomers assemble into two tightly
CC bound homodimers. Interacts with HrcQa (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Note=Or loosely
CC associated with a membrane component, probably HrcQa. {ECO:0000250}.
CC -!- DOMAIN: The HrcQb-C domain interacts with the HrcQa C-terminal domain.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the FliN/MopA/SpaO family. {ECO:0000305}.
