[The molecular cloning of a genetic region determining the surface exclusion system of the F-like plasmid pAP42]. / Molekuliarnoe klonirovanie geneticheskoi oblasti, determiniruiushchei sistemu poverkhnostnogo iskliucheniia F-podobnoi plazmidy pAP42.

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) of this plasmid.
