SignificanceThe formation of cross-alpha amyloids has been shown by crystallographic analysis of the highly cytolytic peptide PSMalpha3, a secreted virulence factor associated with the human pathogen Staphylococcus aureus. However, the relationship of the crystallographic cross-alpha structure to self-assembled filaments of PSMalpha3 and its relevance to other phenol-soluble modulin (PSM) peptides remained an open question. We report the cryo-electron microscopy structural analysis of three nanotubes derived from self-assembly of PSMalpha3 and PSMbeta2 peptides in aqueous solution. In each case, the nanotubes are derived from self-association of cross-alpha amyloid protofilaments. The self-assembly behavior of S. aureus PSMalpha3 and PSMbeta2 peptides provides strong evidence for the importance of the cross-alpha fold in self-assembled peptide and protein structures in general and for PSMs in particular.
