Six conformations of OX1 with the predicted
docking poses of 30
conformations of the C-terminally truncated form of OxA (determined
by NMR and extracted from PDB entry 1WSO).34 Transmembrane
domains 1–7 are colored dark orange, pink, red, purple, dark
red, orange, and light yellow, respectively. Interstrand cross-links
are colored cyan, ECLs dark green, and the C-termini of OxA and OX1
gray.
