Fig. 1. Binding of GLFG and FxFG repeats to Ib442.
Annealed omit F[o] F[c] maps
contoured at 2.5 at the
primary GLFG binding site (A) (site 1, see C) and the primary
FxFG binding site (B). C, the GLFG peptide showed difference
density located at two sites on Ib442. Site 1 (black) was
located between the A-helices of HEAT repeats 5 and 6 and was
also the primary site at which FxFG cores bound, whereas site 2
(red) was located at a contact between two Ib442 chains in the
crystal and was thought to be a crystallization artifact.
