Diagram comparing the genomic context of mcf1 and mcf2-encoding islands in Pa ATCC43949, Pl TT01 and Pseudomonas fluorescens. Genes similar to mcf1 are found in all Photorhabdus strains and also in the plant-associated bacterium P. fluorescens where the mcf1-like toxin encoding gene is called fitD. Note that fitD in P. fluorescens and mcf2 in Pl TT01 are encoded adjacent to ABC transporters, suggesting that type 1 secretion may be responsible for release of the Mcf-like toxin from the bacterial cell.
