The effect of overproduction of MMR proteins on growth-dependent reversion of an episomal TetS allele. The results are the mean number of TetR colonies appearing 2 to 5 days after plating on glycerol minimal medium with tetracycline, determined from 3 to 4 cultures of each strain. Each strain carried both a pACYC- and a pBR-derived plasmid; the genes on the plasmids are listed to the left of the graph. Error bars are ±S.E. Plasmids were as in Fig. 2 except their TetR genes were deleted if required. The control pBR322 TetS plasmid was obtained from S.T. Lovett.
