  • Title: [The genetic regulation of the conjugative properties of plasmid complex pAP18 in E. coli cells].
    Author: Grishina EV, Shchipkov VP, Pekhov AP.
    Journal: Biull Eksp Biol Med; 1993 Jun; 115(6):655-6. PubMed ID: 8104052.
    Abstract:
    Natural plasmid complex pAP18 discovered in E. coli cells consists of F-like plasmid pAP18-1 (Tc, ColV) and N-like plasmid pAP18-2 (Sm) which differ in their genetic transfer. Plasmid pAP18-1 is able to inhibit transfer of plasmid pAP18-2 but not vice versa. These systems are active both in cells of serologically typed and untypable E. coli strains.
