R100 is a plasmid, approximately 90 kilobase pairs (kb) in size, that encodes several
antibiotic resistances, functions involved in conjugal transfer of the plasmid DNA and also …

R6-5 is a low copy number, conjugative, FII incompatibility group plasmid that has a
molecular length of 102 kb and that specifies resistance against several antibiotics …

The replication origin of a group of small plasmids derived from R100 was previously
determined by electron microscopy (Ohtsubo et al., 1977). This region was subjected to …

The nucleotide sequence of the entire region required for autonomous replication and
incompatibility of an R100 plasmid derivative, pSM1, has been determined. This region …

Replicating molecules of plasmid RSF1040, a deletion mutant of R6K, were synthesized in
vitro and analyzed by electron microscopy. Initiation of replication occurs at three unique …

We have constructed two miniplasmids, derived from the resistance plasmid R100. 1. In one
of these plasmids 400 bp of R100. 1 DNA have been replaced by DNA from the transposon …

A small derivative of plasmid R1 was used to integratively suppress a chromosomal dnaA
(Ts) mutation. The strain obtained grew normally at 42° C. The integratively suppressed …

We have cloned the entire r-determinant of the antibiotic resistance plasmid R100. 1 on the
plasmid vectors pCR1 and pSC201. We find that the hybrid plasmids segregate from …

Plasmids serve as good model systems for the study of the regulation of DNA replication
because of their stable inheritance in the cell. The plasmids of enteric bacteria can be …

Plasmid R1 is a low-copy-number plasmid belonging to the IncFII group. The genetics,
biochemistry, molecular biology, and physiology of R1 replication and its control are …
