Mutagenesis of m2G, e2G, FF, and HF in the four strains of <i>E. coli</i> cells lacking or expressing DinB or AlkB.

<p>Each panel (<b>A</b> to <b>D</b>) corresponds to the <i>E.coli</i> strain indicated at the top of the graph. Genomes containing m3C, undamaged G, and an approximately equimolar mixture of unmodified G/A/T/C bases at the site of inquiry (denoted as GATC) were used as controls. Genomes containing the lesions of interest were transfected into <i>E. coli</i> in triplicate. The percentage of G, A, T, and C at the lesion site reveals the mutagenicity of the lesions, with error bars representing one standard deviation. All mutagenesis data are summarized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0094716#pone.0094716.s001" target="_blank">Table S2 in File S1</a>.
