Prediction of possible structural changes for the N terminal portion of the resolvase encoded by gene hin in S. typhimurium LT2 when a leucine is substituted by serine due to an AGT → TGT transversion in S. paratyphi C. (A) Modeled structure in S. typhimurium; and (B) Modeled structure in S. paratyphi C. As the amino acid substitution takes place in a region connecting two helices, the secondary protein structure is not affected.
