SIGNAL RECOGNITION PARTICLE RECEPTOR FROM E. COLI
Overview
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.
