    Multiple alignment of amino acid sequences of OpdA proteins found in different bacteria: Y. pseudotuberculosis (accession number CAH23054.1), E. coli (synonym name PrlC, accession number P27298.3), Salmonella enterica serovar Typhimurium (accession number P27237.1) and Haemophilus influenzae (accession number P44573.1). Amino acid residues corresponding to Zn2+ binding motif (by similarity to E. coli OpdA) are highlighted in red. A Tyr residue corresponding to Tyr607 of E. coli OpdA shown to be essential for enzyme activity and specificity is also highlighted (in green). (JPG 525 kb

    PCR analysis of Y. psedutuberculosis YPIII wild type (lane 2), and three clonal isolates of the ΔopdA mutant (lanes 3–5) using gene specific primers Yptb3816_for (ATGACAAACCCGCTGTTGACT) and Yptb3816_rev (TTAGCCCTTAATACCGTAATGAC). The expected product size after deletion is 1.2 kb, corresponding to a deletion of almost the entire gene sequence (1.9 out of 2.1 kb) plus 1 kb corresponding to the inserted kan r resistance gene. Lane 1, DNA size ladder 1 kb plus (Life Technologies). (JPG 69 kb
