CC   -!- FUNCTION: Disorganizes the host nucleoid and inhibits replication, but
CC       without host DNA cleavage or degradation. Only the architecture of the
CC       nucleoid is affected. May act on the host chromosomal sequences that
CC       determine the structure of the nucleoid. Binds to dsDNA but not to
CC       ssDNA. {ECO:0000269|PubMed:9748458}.
