| Description | The ligand-binding domain of metabotropic glutamate receptor 7 has been overexpressed, purified, and crystallized by the hanging-drop vapour-diffusion method. A complete data set has been collected to 3.30 Å. Glutamate is the major excitatory neurotransmitter and its metabotropic glutamate receptor (mGluR) plays an important role in the central nervous system. The ligand-binding domain (LBD) of mGluR subtype 7 (mGluR7) was produced using the baculovirus expression system and purified from the culture medium. The purified protein was characterized by gel-filtration chromatography, SDS–PAGE and a ligand-binding assay. Crystals of mGluR7 LBD were grown at 293 K by the hanging-drop vapour-diffusion method. The crystals diffracted X-rays to 3.30 Å resolution using synchrotron radiation and belong to the trigonal space group P3121, with unit-cell parameters a = b = 92.4, c = 114.3 Å. Assuming the presence of one protomer per crystallographic asymmetric unit, the Matthews coefficient V M was calculated to be 2.5 Å3 Da−1 and the solvent content was 51%. |
