Replication Functions Encoded by the Plasmid pSClOl
We describe the mapping of several genetic loci involved in the replication of the pSClOl plasmid. These include the origin of replication and a short segment of DNA that encodes a pSClOl incompatibility function. This short segment lies within the origin region. Flanking the incompatibility segment are two loci, repA and repB, which are required for replication. The product of the repA locus is shown to be trans-acting.
