Sj. Billington et al., THE ARCANOBACTERIUM (ACTINOMYCES) PYOGENES PLASMID PAP1 IS A MEMBER OF THE PIJ101 PJV1 FAMILY OF ROLLING CIRCLE REPLICATION PLASMIDS/, Journal of bacteriology, 180(12), 1998, pp. 3233-3236
The 2.4-kb plasmid pAP1 from Arcanobacterium (Actinomyces) pyogenes ha
d sequence similarity within the putative replication protein and doub
le-stranded origin with the pIJ101/pJV1 family of plasmids. pJGS84, a
derivative of pAP1 containing a kanamycin resistance gene, was able to
replicate in Escherichia coli and Corynebacterium pseudotuberculosis,
as well as in A. pyogenes. Detection of single-stranded DNA intermedi
ates of pJGS84 replication suggested that this plasmid replicates by t
he rolling circle mechanism.
