FIG. 2.
Organization of pvdXYS genes. The organization of the pvdX, pvdY, and pvdS genes from P. aeruginosa strain Pa4 (top) and strain PAO (bottom) is shown. The genes are not drawn to scale; the pvdY protein-coding sequence is 468 bp, and the pvdYII protein-coding sequence is 912 bp. The stop codons for pvdX and pbdS are in bold.
