Figure 8. Ribbon views of 20 linker structures seen in
crystal and NMR structures of pairs of SCR domains. The most
common linker conformations are shown in yellow. Four linker
conformations that deviate from the most common ones are denoted
by green ribbons and labelled a to d. Four linkers that show
less conformational deviations are labelled w to z. The eight
residue and three residue linkers are shown in purple and red,
respectively. The left-hand view corresponds to the SCR-1
structure of b2GPI, in which the linkers are shown superimposed
at the C terminus at Cys58. The right-hand view corresponds to
the SCR-2 structure of b2GPI, in which the linkers are
superimposed at the N terminus at Cys4.
