eIF4G uses a conserved Tyr-X-X-X-X-Leu-phi segment (where X is variable and phi is hydrophobic) to recognize eIF4E during cap-dependent translation initiation in eukaryotes. High-resolution X-ray crystallography and complementary biophysical methods have revealed that this eIF4E recognition motif undergoes a disorder-to-order transition, adopting an L-shaped, extended chain/alpha-helical conformation when it interacts with a phylogenetically invariant portion of the convex surface of eIF4E ...
