Summary We have identified gene products corresponding to hlyC, hlyA and hlyD encoded by the Escherichia coli haemolytic determinant 2001 of human origin cloned into the recombinant plasmid pLG570. The product of hlyC is required for the “activation” of the inactive 107K polypeptide encoded by the hlyA gene. the activated 107K protein constitutes the active haemolysin secreted into the medium. hlyB and hlyD are separate regions defined by complementation studies and encode functions essential for the export of haemolysin with hlyD encoding a 53K protein. Complementation studies using subclones and Tn5 insertions into pLG570 have revealed the presence of two major promoters upstream of hlyC and hlyD which transcribe the four hly genes in the same direction. Finally, we were able to reconstitute the complete haemolysin system from three different plasmids encoding hlyC, hlyA and hlyB+hlyD, respectively.
