RT entry nuclease and the competence-specific 18-kilodalton protein.";

CC -!- FUNCTION: By degrading DNA that enters the cell, plays a role in the
CC competence of cells to be transformed. Degrades both double-stranded,
CC linear and covalently closed circular DNA.
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Note=Mn(2+) ion stimulates activity.;
CC -!- ACTIVITY REGULATION: The activity can be inhibited by the 18 kDa
CC competence-specific protein nin.
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; Single-pass membrane protein.
CC -!- SIMILARITY: To B.subtilis NucB. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAA06431.1; Type=Erroneous initiation; Evidence={ECO:0000305};
CC Sequence=BAA08977.1; Type=Erroneous initiation; Evidence={ECO:0000305};
