CC   -!- FUNCTION: Plays a role in the competence of cells to be transformed. It
CC       inhibits the activity of the DNA-entry nuclease.
CC   -!- SUBUNIT: This protein is a subunit of a 75 kDa protein complex, which
CC       governs binding and entry of donor DNA. The complex is a tetramer of
CC       two subunits of the DNA-entry nuclease and two subunits of a
CC       competence-specific protein. Only the complex is able to bind ds- and
CC       ss-DNA.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein.
