FIG 2.

Representative genetic organizations of the paeM4 locus in Pseudomonas aeruginosa strains. Synteny is represented by sequence conservation (gray shading). Genes are represented by arrows, and a paeM4 fragment is shown as a shorter rounded shape. Functions of genes and gene parts (if known) are specified by color in the legend. The receptor-binding domain (RBD) of PaeM4 includes the TonB box that is part of a short region at the amino terminus of the encoded protein. The candidate immunity partner (Imm) PmiC is encoded downstream of paeM4, in the opposite direction. Dotted lines indicate the lack of an equivalent nucleotide sequence.
