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       hrcQb (By similarity). {ECO:0000250, ECO:0000269|PubMed:9190801}.
CC   -!- SUBUNIT: Interacts with hrcQb. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Peripheral
CC       membrane protein {ECO:0000250}.
CC   -!- DOMAIN: The HrcQa-C domain interacts with the hrcQb C-terminal domain.
CC       {ECO:0000250}.
