Crystallization and preliminary X-ray crystallographic studies of human 2',3'-cyclic nucleotide 3'-phosphodiesterase.
The catalytic fragment of human 2',3'-cyclic nucleotide 3'-phosphodiesterase (hCNP-CF) has been crystallized by the hanging-drop vapour-diffusion method using polyethylene glycol 300 as the precipitating agent. The crystals belong to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 44.39, b = 55.35, c = 78.76 A. There is one molecule per asymmetric unit. The crystals diffract to at least 1.8 A resolution using synchrotron radiation and are suitable for X-ray structure analysis at high resolution.
