Fig. 5From: New indicator Escherichia coli strain for rapid and accurate detection of supF mutationssupF mutation spectra of pZ189-RM introduced into KS40/pOF105 and RF01. The upper strand sequence of supF is shown, and single base substitutions observed in supF mutants of KS40/pOF105 and RF01 are shown above and below the sequence, respectively. Dotted and dashed underlines represent promoter and supF tRNA coding sequences, respectively; gray font indicates the pre-tRNA sequence; thin letters indicate mutants that formed smaller colonies; and bold letters indicate mutants that formed normal-sized coloniesBack to article page
