Molecular cloning of genetic region of F-like plasmid pAP42, coding its surface exclusion system (system Six V) was performed. Restriction and genetic analysis of recombinant plasmids showed that six V locus is situated in Sal I-fragment f5 (4.2 MD)

[Mutations of the genetic region Fin of the F-like plasmid pAP18-1]

Autor: N I, Buianova, V P, Shipkov, A P, Pekhov

Publikováno v: Biulleten' eksperimental'noi biologii i meditsiny. 112(11)

With help of nitrosoguanidine 60 mutants of F-like plasmids pAP18-1 drd::Tn 5 and pAP18-1::Tn 9 were induced which determined resistance of E. coli cells of specific phage MS2. Mutational changes in fin-locus of those plasmids were accompanied by phe

[The role of host cells in the genetic regulation of plasmid transfer in Escherichia coli]

Autor: D E, Kulumbetova, V P, Shipkov, A P, Pekhov

Publikováno v: Biulleten' eksperimental'noi biologii i meditsiny. 106(8)

The role of serologically typed and nontyped E. coli cells in the expression of genetic regulation systems activity for repressed plasmids transfer (types fin OP, fin U, fin V) was studied. It is shown that the inhibiting action of such plasmids on t

[Atypical incompatibility of the F-like factors of pA22-4, pAP39 and pA41 genetic transfer with the F-group incompatibility plasmids]

Autor: A P, Pekhov, V P, Shipkov, V N, Reshetnikova, E V, Gubar', N A, Drobysheva

Publikováno v: Biulleten' eksperimental'noi biologii i meditsiny. 90(8)

A study was made of compatibility of three F-like factors of the genetic transfer (pAP22-4, pAP39, pAP41) identified in the cells of serologically typed E. coli strains with F-group incompatibility reference plasmids. The factors of pAP22-4 and pAP41
