Abstract

An NAD(P)H-dependent carbonyl reductase specifically expressed in thyroidectomized chicken fatty liver was crystallized using the sitting-drop vapour-diffusion method with polyethylene glycol 300 as the precipitant. The crystals belonged to the monoclinic space group C2, with unit-cell parameters a=104.26, b=81.32, c=77.27 Å, β=119.43°, and diffracted to 1.86 Å resolution on beamline NE3A at the Photon Factory. The overall Rmerge was 5.4% and the data completeness was 99.4%.

摘要

一种在甲状腺切除的鸡脂肪肝中特异性表达的NAD(P)H依赖性羰基还原酶,采用坐滴气相扩散法,以聚乙二醇300作为沉淀剂进行结晶。晶体属于单斜晶系空间群C2,晶胞参数为a = 104.26、b = 81.32、c = 77.27 Å,β = 119.43°,在光子工厂的NE3A光束线上衍射至1.86 Å分辨率。整体合并R因子为5.4%,数据完整性为99.4%。
