| - | The bacterial signal recognition particle (SRP) receptor, FtsY, participates with the SRP in co-translation targeting of proteins. Multiple crystal structures of the NG domain of E. coli FtsYNG have been determined at high-resolution (1.22-1.88A), in the nucleotide-free (apo) form as well as bound to GDP and non-hydrolysable GTP analogues. The combination of high-resolution and multiple solved structures of FtsYNG in different states revealed a new sensor-relay system of this unique GTPase receptor. A nucleotide sensing function of the P-loop assists FtsYNG in nucleotide-binding and contributes to modulate nucleotide binding properties in SRP GTPases. A reorganization of the other G-loops and the insertion binding domain (IBD) is observed only upon transition from a diphosphate to a triphosphate nucleotide. The role of a magnesium ion during the GDP and GTP-bound states has also been observed. The binding of magnesium in the nucleotide site causes the reorientation of the beta- and gamma- phosphate groups toward the jaws of the P-loop and stabilizes the binding of the nucleotide, creating a network of hydrogen and water-bridge interactions.

Function
FTSY_ECOLI Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components.[1] [2] [3] [4] [5] [6]
