The crystal structure of the region spanning residues 95-146 of the rotavirus nonstructural protein NSP4 from the asymptomatic human strain ST3 was determined at a resolution of 2.5 Å. Severe diffraction anisotropy, rotational pseudosymmetry and twinning complicated the refinement of this structure. A systematic explanation confirming the crystal pathologies and describing how the structure was successfully refined is given in this report.
测定了来自无症状人类毒株ST3的轮状病毒非结构蛋白NSP4中95 - 146位残基区域的晶体结构,分辨率为2.5 Å。严重的衍射各向异性、旋转假对称性和孪晶使该结构的精修变得复杂。本报告给出了一个系统的解释,证实了晶体的异常情况,并描述了该结构是如何成功精修的。
