FIG. 2.

Alignment of the deduced amino acid sequences of the integrases of Y. pestis (first line), Y. pseudotuberculosis (second line), STEC strain 3172/97 (third line), and STEC strain 5720/96 (fourth line). Translation of the latter sequence was performed without consideration of the frameshift resulting from the deletion of 347 bp. Bold letters represent differences in the amino acid sequence from the sequence of Y. pestis in the first line. Dashes in the last line indicate amino acid residues that are not present in this sequence (deletions). The deduced amino acid sequences of the Y. pestis and Y. pseudotuberculosis integrases are based on references 7 and 13.
