ClustalW alignment generated percentage sequence identities of paaL genes (top section) and respective promoters (bottom section) from a number of Pseudomonas species harbouring the PaCoA catabolon. CA-3, F1, GB-1, KT2440, ST, W619 and Y2 represent individual P. putida strains. The Pf5 and ST strains are members of the P. fluorescens group while L48 represents P. entomophila L48.
