A complex profile of protein elongation: translating chemical energy into molecular movement

AbstractThe recently solved structures of the protein elongation factor complexes, EF-Tu–GDPNP–phenylalanyl-tRNA and EF-T–Ts, complete the atomic profile of four EF-Tu conformational states. As a set, the three-dimensional structures suggest an atomic model for movement during protein elongation and, by molecular mimicry with EF-G, translocation as well
