RESUMO
A database search revealed extensive sequence similarity between Streptomyces lividans plasmid pIJ101 and Streptomyces plasmid pSB24.2, which is a deletion derivative of Streptomyces cyanogenus plasmid pSB24.1. The high degree of relatedness between the two plasmids allowed the construction of a genetic map of pSB24.2, consisting of putative transfer and replication loci. Two pSB24.2 loci, namely, the cis-acting locus for transfer (clt) and the transfer-associated korB gene, were shown to be capable of complementing the pIJ101 clt and korB functions, respectively, a result that is consistent with the notion that pIJ101 and the parental plasmid pSB24.1 encode highly similar, if not identical, conjugation systems.
