Notes:
Ygr203p, a 148-residue protein encoded by the ygr203w gene of Saccharomyces cerevisiae, is a homologue of the yeast Acr2 arsenate reductase encoded by the acr2 (or ypr200c) gene. It also shows significant sequence similarity to the human cell-cycle control Cdc25 phosphatase family. It has been overexpressed in soluble form in Escherichia coli with a His6 tag at its C-terminus. The recombinant protein has been crystallized at 296 K using sodium chloride as precipitant. The crystals belong to the orthorhombic space group P212121, with unit-cell parameters a = 40.48, b = 50.95, c = 91.95 Å. The asymmetric unit contains a monomer, giving a crystal volume per protein mass (Vm) of 2.61 Å3 Da−1 and a solvent content of 53.8%. The crystals diffract to better than 1.9 Å resolution with Cu Kα X-rays. They are therefore suitable for high-resolution structure determination.
