Case study: Palinsight displaying the shared palindrome in sequences 1 to 10 of the working set. Using Palinsight we have detected a shared palindrome in these extragenic sequences upstream genes encoding AcrR similar proteins. The same palindrome is conserved for all Escherichia coli and Shigella flexneri sequences (extragenic sequences 1–6). Another slightly different palindrome is conserved in Salmonella enterica and Salmonella typhimurium (extragenic sequences 7–10).
