Crystallization and preliminary x-ray studies of TON_0559, a putative member of the haloacid dehalogenase (HAD) superfamily from Thermococcus onnurineus NA1

Abstract

To elucidate the molecular basis underlying their broad substrate specificity and reaction mechanism of the enzymes belonging to the haloacid dehalogenase (HAD) superfamily, TON_0559, a putative HAD subfamily protein from a hyperthermophilic archaeon Thermococcus onnurineus NA1, was expressed, purified and crystallized. X-ray diffraction data were collected to 2.0 Å resolution. The space group is C2, with unit cell parameters a = 121.2 Å, b = 62.9 Å, c = 37.5 Å and β= 106.5°. © 2008 Bentham Science Publishers Ltd.
