Definition of a minimal plasmid stabilization system from the broad-host-range plasmid RK2.

Journal of bacteriology - 1 Dec 1992

Roberts R C, Helinski D R

Abstract excerpt

The stable inheritance of the broad-host-range plasmid RK2 is due at least in part to functions within a region located at coordinates 32.8 to 35.9 kb, termed the RK2 par locus. This locus encodes four previously identified genes in two operons (parCBA and parD; M. Gerlitz, O. Hrabak, and H. Schwab, J. Bacteriol. 172:6194-6203, 1990, and R. C. Roberts, R. Burioni, and D. R. Helinski, J. Bacteriol. 172:6204-6216,...
