Purification, crystallization and preliminary X-ray diffraction analysis of a cystathionine beta-synthase domain-containing protein, CDCP2, from Arabidopsis thaliana

초록

Cystathione beta-synthase domain-containing protein 2 (CDCP2) from Arabidopsis thaliana has been overexpressed and purified to homogeneity. As an initial step towards three-dimensional structure determination, crystals of recombinant CDCP2 protein have been obtained using polyethylene glycol 8000 as a precipitant. The crystals diffracted to 2.4 angstrom resolution using synchrotron radiation and belonged to the trigonal space group P3(1)21 or P3(2)21, with unit-cell parameters a = b = 56.360, c = 82.596 angstrom, alpha = beta = 90, gamma = 120 degrees. The asymmetric unit contains one CDCP2 molecule and the solvent content is approximately 41%.
