Use of the Artemis comparison tool to analysis Tn 4371 -like ICE sequences of Tn 4371, Shewanella sp. ANA-3, C. litoralis KT71, S. maltophilia K279a and Thioalkalivibrio sp. HL-EbGR7. All ICEs analysed shared extensive sequence homology, and general gene order. Arrows on top delimit the functional regions whose order is well conserved in all Tn4371-like ICEs.
