'''SIGNAL RECOGNITION PARTICLE RECEPTOR FROM E. COLI'''<br />


==Overview==
==SIGNAL RECOGNITION PARTICLE RECEPTOR FROM E. COLI==
FtsY is the docking protein or SR alpha homologue in E. coli. It is involved in targeting secretory proteins to the cytoplasmic membrane by interacting with the signal recognition particle, controlled by guanosine 5'-triphosphate. Two different constructs have been used in crystallization studies: the full-length protein and a truncated fragment with a his-tag at the C terminus. Only the second construct resulted in crystals suitable for x-ray diffraction. The crystals belong to the monoclinic space group P2(1) with cell dimensions a = 32.20 A, b = 79.57 A, c = 59.21 A, and beta = 94.45, and contain one molecule per asymmetric unit. At cryogenic temperatures the crystals diffract to a resolution limit of 2.5 A by using a rotating anode, and beyond 1.8 A by using synchrotron radiation.

Structural highlights

1fts is a 1 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

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]
