Abstract excerpt

The signal recognition particle (SRP) initiates the co-translational targeting of proteins to the plasma membrane in bacteria by binding to the N-terminal signal sequence emerging from the translating ribosome. SRP in Escherichia coli is composed of one protein, Ffh, and 4.5S RNA. In the present work, we probe the structure of Ffh alone and in the complex with 4.5S RNA by measuring distances between different...
