AbstractWe have characterized a region in the streptococcal plasmid pLSl located between nucleotides 4103 and 4218 which is a signal involved in the conversion of single stranded intermediates of replication to double stranded plasmid forms. This region has a large axis of dyad symmetry resulting in the formation of a secondary structure as revealed by the location of endonuclease S1-cleavage sites in supercoiled covalently closed circular pLS1 DNA. Deletions affecting this region caused a fivefold reduction in plasmid copy number, plasmid instability and the accumulation of single-stranded DNA intermediates. The conversion signal of pLS1 has homologues in other staphylococcal plasmids, sharing a consensus sequence located in the loop of the signal. Computer assisted analysis showed that the signal detected in pLS1 has a high degree of homology with the complementary strand origin of the Escherichia coli single stranded bacteriophages øX174 and M13.
