Fig. 8. Proposed mechanism of attraction of bacteriocins that contain the saposin-like fold. Some of these bacteriocins (e.g. AS-48) are known to form dimers (A) but others remain monomers (B), as they initially interact with the cell membrane of bacteria. They may aggregate later to form pores. Diagrams are recreated from diagrams which have been proposed for some SAPLIP peptides as seen in reference.25.
