Figure 2. SRP-FtsY GTPase complex relocalization to the SRP RNA distal end.

Figure 2

A. Crystal structure of SRP in complex with FtsY trapped with GMPPCP. Full-length 4.5S SRP RNA in tan, with the tetraloop and distal end indicated. Ffh in violet with M and NG domains indicated, and FtsY(NG) in green. PDB: 2XXA. The figure was prepared using PyMOL. B. E. coli 4.5S SRP RNA secondary structure. The tetraloop and distal end GTPase complex binding site are indicated in tan boxes.
