Confirmation of the long-range interactions in wild-type katG DNA by compensatory substitutions. (A) Proposed hairpin structure of the wild-type (WT) 391 nt katG DNA fragment. The G41·C385 base pair is shown in bold. (B) The TaqExo cleavage products of the WT/C385G and G41C/C385G 391 nt katG DNA fragments carrying the C385G substitution. The 37 nt cleavage product and its position in the structures are shown by arrows. M, size markers. The nucleotide positions discussed in the text are indicated.
