CC   -!- FUNCTION: Enables the recognition and targeting of unfolded and
CC       aggregated proteins to the ClpC protease or to other proteins involved
CC       in proteolysis. Acts negatively in the development of competence by
CC       binding ComK and recruiting it to the ClpCP protease. When
CC       overexpressed, inhibits sporulation. Also involved in Spx degradation
CC       by ClpC (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- DOMAIN: The N-terminal domain has binding sites for ComK and probably
CC       for unfolded/aggregated proteins; the C-terminal domain interacts with
CC       ClpC.
CC   -!- SIMILARITY: Belongs to the MecA family. {ECO:0000305}.
