Crystallization and preliminary X-ray diffraction analysis of glutamate dehydrogenase from an aerobic hyperthermophilic archaeon, Aeropyrum pernix K1.
Glutamate dehydrogenase from an aerobic hyperthermophilic archaeon, Aeropyrum pernix K1, was crystallized by the hanging-drop vapour-diffusion method using polyethylene glycol (PEG) 400 as the precipitant. The crystals belong to the hexagonal space group P6(3), with unit-cell parameters a = b = 98.9, c = 394.8 A, alpha = beta = 90, gamma = 120 degrees. The asymmetric unit contained one hexamer of the enzyme, giving a crystal volume per enzyme mass (V(M)) of 1.98 A(3) Da(-1) and a solvent content of 37.3%. The X-ray diffraction data were collected to a resolution of 3.0 A at the BL6B beamline in the Photon Factory with an overall R(sym) of 13.8% and a completeness of 87.1%.
