Abstract
Caedibacter taeniospiralis 51 carries at least two plasmids, pKAP51 and pKAP52. The smaller plasmid, pKAP51, contains 43 kilobase pairs. The larger plasmid, pKAP52, contains more than 110 kilobase pairs. Relative positions of recognition sequences for seven different restriction endonucleases were determined, and a physical map of pKAP51, consisting of a total of 28 restriction sites, was constructed.
