D-Aspartate oxidase (DDO) from porcine kidney was crystallized by the sitting-drop vapour-diffusion method using PEG 8000 as a precipitant. The crystal belonged to space group P2(1), with unit-cell parameters a = 79.38, b = 144.0, c = 80.46 Å, β = 101.1°, and diffracted to 1.80 Å resolution. Molecular-replacement trials using the structure of human D-amino-acid oxidase, which is 42% identical in sequence to DDO, as a search model provided a satisfactory solution.
使用聚乙二醇8000作为沉淀剂,通过坐滴气相扩散法使来自猪肾的D-天冬氨酸氧化酶(DDO)结晶。该晶体属于空间群P2(1),晶胞参数为a = 79.38、b = 144.0、c = 80.46 Å,β = 101.1°,衍射分辨率达到1.80 Å。以与DDO序列有42%同一性的人D-氨基酸氧化酶的结构作为搜索模型进行分子置换试验,得到了令人满意的结果。
