Stability of RK2 minireplicons in protease deficient and Lon-overproducing strains

Escherichia coli C600 strain	Plasmid loss rate (% per generation)^a
Wild-type^b	0.12 ± 0.01
clpP^−b	0.24 ± 0.02
lon^−b	0.33 ± 0.01
Wild-type (pBAD24)^c	1.46 ± 0.05
Wild-type (pBADLon)^c	3.23 ± 0.94

^aGiven values are means from three independent repeats of each experiment.

^bStability of pRR10 minireplicon was analyzed in C600 and its mutant derivatives cultured in antibiotic-free medium

^cStability of pTJS42 minireplicon was analyzed in wild-type C600 strain cells carrying either pBAD24 or pBADLon cultured in ampicillin-containing medium.
