Fig. 3From: The carbapenem resistance gene blaOXA-23 is disseminated by a conjugative plasmid containing the novel transposon Tn6681 in Acinetobacter johnsonii M19Linear comparison of structures harbouring blaOXA-23. IRR, right inverted repeat; IRL, left inverted repeat. All block arrows indicate length and orientation. The numbers in each block arrow or box represent the nucleotide sequence identity compared with Tn6681. The distance between ISAba1 or ΔISAba1 and the blaOXA-23 start codon is indicated by the number of base pairs below a curved arrow. Direct repeat sequences are indicatedBack to article page
