Lagging-strand replication from the ssoA origin of plasmid pMV158 in Streptococcus pneumoniae: in vivo and in vitro influences of mutations in two conserved ssoA regions.

Abstract excerpt

The streptococcal plasmid pMV158 replicates by the rolling-circle mechanism. One feature of this replication mechanism is the generation of single-stranded DNA intermediates which are converted to double-stranded molecules. Lagging-strand synthesis initiates from the plasmid single-stranded origin, sso. We have used the pMV158-derivative plasmid pLS1 (containing the ssoA type of lagging-strand origin) and a set...
