1BJ2, 2BJ2 - PubMed Abstract: 
Replication of the ColE1 plasmid of Escherichia coli is regulated by the interaction of sense and antisense plasmid-encoded transcripts. The antisense RNA I negatively regulates the replication of the plasmid by duplex formation with complementary RNA II. The interaction is initiated by the formation of a double helix between seven-nucleotide loops from each RNA and is stabilized by binding of the RNA one modulator (ROM) protein. The ROM protein is thought to recognize a specific RNA structure, regardless of sequence.
