A mini-replicon was obtained for the caprolactam/salicylate degradation plasmid pBS270 (105kb) of incompatibility group P-7 from Pseudomonas bacteria, and its nucleotide sequence was determined. A new gene that encodes a TrfA-like replication initiator was found on this replicon. The level of homology between this replication initiator and known proteins of the TrfA family suggests that the obtained replicon can be classified as IncP-1-like. The pBS270mini was shown to be chimeric.
