Figure 1.

Comparison of selected Staphylococcal aureus and Streptococcus pyogenes enterotoxin and enterotoxin-like structures. Staphylococcal aureus enterotoxins include SEA (PDB code: 1ESF), SEB (PDB code: 1SE4) and TSST-1 (PDB code: 2QIL). The Staphylococcal aureus enterotoxin-like protein shown is SSL4 (PDB code: 4DXF). Two Streptococcal pyogenes enterotoxins are displayed: SpeA1 (PDB code: 1UUP) and SpeC (PDB code: 1KTK). The structures are shown as a ribbon plot with α-helices, β-strands and loops coloured in red, yellow, and green, respectively.
