Genetic characteristics of hypermotile A. baumannii strains. (A) Using whole-genome sequencing of the ATCC 17978 and 17978hm strains, an insertion sequence (IS) element was identified in a position unique to A. baumannii strain 17978hm. The sequence as found in strain 17978hm has been provided; the target sites of the IS element are shown in red, and the inverted repeat section of the IS element is underlined. (B) Amino acid sequences of the DNA binding region of the H-NS-like proteins from strain ATCC 17978, HNSmut88, Mycobacterium tuberculosis, Salmonella, and E. coli are displayed. Positively charged residues that may be involved in DNA interactions are shown in red. The arginine (R) residues positioned outside the DNA binding domain are in bold. The lysine (K) in position 88 in strain ATCC 17978 mutated to an isoleucine (I) in strain HNSmut88 is boxed in blue.
