Abstract

Minireplicons from the I-complex plasmids R387 (IncK) and pIE545 (IncZ) were constructed, and the nucleotide sequences of their replication regions were compared with that of the B plasmid, pMU720. The coding sequence of the putative replication protein, RepA, of each plasmid was located. RepA of K and B plasmids were homologous, whereas RepA of Z resembled RepA1 of FII plasmid. Sequences upstream of RepA were conserved in the three I-complex plasmids. Group B and Z plasmids were incompatible.
