Abstract
The signal recognition particle (SRP) recognizes and binds the signal sequence of nascent proteins as they emerge from the ribosome. We present here the 3.0-Å structure of a signal sequence bound to the Methanococcus jannaschii SRP core. Structural comparison with the free SRP core shows that signal-sequence binding induces formation of the GM-linker helix and a 180° flip of the NG domain-structural changes that ensure a hierarchical succession of events during protein targeting.
