Abstract: “Black holes” in the genomes of bacterial pathogens represent deletions of “anti-virulence” genes, i.e. genes that are detrimental to a pathogenic lifestyle. Identification of the missing genetic loci in the “black hole” identifies genes that are incompatible with the bacteria's pathogenicity. These genes, their gene products, and compounds generated by the enzymatic action of these gene products represent potential new compounds that are inhibitory to the bacterial pathogen and thus useful as pharmaceuticals. The utility of this concept is demonstrated in the missing gene for lysine decarboxylase, and the resulting inhibitory activity of cadaverine (the diaminoalkyl reaction product of lysine decarboxylase) on the Shigella enterotoxins. Diaminoalkyl compounds are therefore potent inhibitors of E. coli and Shigella spp. enterotoxins. Lysine decarboxylase generated from the gene cadA results in attenuation of the enterotoxic effects.
