Figure 5. MHC-SAG-TCR ternary signaling complexes mediated by
(a) TSST-1, (b) SEB, (c) SpeC, and (d) SEK. Colors are as
follows: MHC α subunit, green; MHC β subunit, blue; antigenic
peptide, gray; TCR α chain, orange; TCR β chain, red; SAGs,
yellow. For clarity, the MHC-SAG-TCR complexes mediated by (c)
SpeC and (d) SEK are rotated approximately 90° clockwise
about the vertical axis of the page relative to those mediated
by (a) TSST-1 and (b) SEB.
