FIG. 1.

Comparison of P. aeruginosa ParB with the other well-studied chromosomal members of the ParB family (P. aeruginosa, Pa; P. putida, Pp; B. subtilis, Bs; C. crescentus, Cc; S. coelicolor, Sc). A black background indicates homology in all five proteins, and a gray background indicates homology in three or four proteins. Regions of conservation are underlined; a thick line corresponds to previously identified blocks (54), and a thin line corresponds to blocks identified here (for the first time). A broken line indicates the proposed linker region referred to in the text. Positions defining the ends of the deletions (see Fig. 3) are marked with coordinate numbers and letters for cross-referencing.
