CC   -!- FUNCTION: Degrades both double-stranded linear and covalently closed
CC       circular DNA. Likely to play a scavenging role in order to supply
CC       nutrients under starvation conditions.
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC       Note=Mn(2+) ion stimulates activity.;
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- DEVELOPMENTAL STAGE: Sporulation-specific.
CC   -!- SIMILARITY: To B.subtilis NucA/ComI. {ECO:0000305}.
