Abstract

The 5.6-kilobase-pair cryptic plasmid, pAM7, of Streptococcus mutans LM7 was cloned into Escherichia coli plasmids or a shuttle plasmid to examine whether the plasmid encodes bacteriocin. Plasmid pAM7 encoded proteins with molecular weights of 30,000, 22,000, and 12,000, but none of them appeared to be bacteriocin.
