Figure 1

The defective mutL alleles with alternations in the copy number of the 6-bp repeat GCGGGC in populations of S. typhimurium (9052D1) and E. coli (Ara-4 and Ara-2). The mutL sequences of wild type S. typhimurium LT2 and E. coli B, both containing the three tandem repeats, are shown as references. Also shown is the amino acid sequence of the corresponding section of the deduced MutL protein. The location of the three tandem repeats is shown on the mutL gene at the top. The numbering given is for the nucleic acid sequences of S. typhimurium LT2 and E. coli B.
