ABSTRACT
A phosphatidylinositol-specific phospholipase C (PI-PLC) that is unique to the pathogenic Listeria species L. monocytogenes and L. ivanovii has been detected. Deletion analysis performed with Escherichia coli recombinants expressing PI-PLC activity together with maxicell analysis showed that a 34 kDa polypeptide was responsible for this activity. Nucleotide sequencing revealed that the gene encoding this polypeptide comprises 317 amino acid residues with a 22-amino-acid signal peptide. This gene, designated pic for phosphatidylinositol-specific phospholipase C, is located back to back with the listeriolysin gene on the chromosome of L. monocytogenes where these genes are transcribed by divergent non-overlapping promoters. Expression of the pic gene is dependent on the product of the prfA gene, which also regulates expression of the listeriolysin gene in L. monocytogenes.
