FIG. 2.

Amino acid alignment of the putative transposase protein of IS1597 from P. multocida with transposase proteins of RSBst-alpha from B. stearothermophilus (10), IS982 from L. lactis subsp. cremoris (16), iso-IS982 from L. lactis (14), an IS982-like element from L. lactis biovar diacetylactis (5), a DNA-binding protein of L. helveticus (13), and part of a not further specified putative protein from P. gingivalis (12). Asterisks mark translational stop codons. Black boxes indicate identical amino acids and gray boxes represent conservative exchanges (1, 6) compared to those present in the 228-aa protein of IS1597.
