The crystal structure of the NTF2-like domain of the Drosophila homolog of Ras GTPase SH3 Binding Protein (G3BP), Rasputin, was determined at 2.7Å resolution. The overall structure is highly similar to nuclear transport factor 2: It is a homodimer comprised of a β-sheet and three α-helices forming a cone-like shape. However, known binding sites for RanGDP(More)
Ras GTPase Activating Protein SH3 Domain Binding Protein (G3BP) is a potential anti-cancer drug target implicated in several cellular functions. We have used protein crystallography to solve crystal structures of the human G3BP1 NTF2-like domain both alone and in complex with an FxFG Nup repeat peptide. Despite high structural similarity, the FxFG binding(More)
The nuclear transport factor 2-like (NTF2-like) domain of human G3BP1 was subcloned, overexpressed in Escherichia coli and purified. Crystals were obtained using the hanging-drop vapour-diffusion method. Diffraction data were collected to 3.6 Å resolution using synchrotron radiation. The crystals belonged to the hexagonal space group P6(3)22, with unit-cell(More)
Two mutant dCTP deaminase-dUTPases from Methanocaldococcus jannaschii were crystallised and the crystal structures were solved: E145A in complex with the substrate analogue alpha,beta-imido-dUTP and E145Q in complex with diphosphate. Both mutant enzymes were defect in the deaminase reaction and had reduced dUTPase activity. In the structure of E145Q in(More)
