日本血吸虫26 kDa谷胱甘肽转移酶(Sj26)是一种潜在的抗血吸虫疫苗抗原,已以非连接形式结晶。重组菌株Sj26的产生菌为Sj26。不使用谷胱甘肽亲和层析柱,以便于制备未连接的酶。该重组蛋白包含Sj261,2的全部218个残基和与C末端相连的13个残基。以硫酸铵为沉淀剂,在pH值为5.6的条件下,采用气相扩散法制备了重组Sj26晶体。晶体属于六方空间群P6322,晶胞尺寸sa=b=125.2ä,c=72.0o,每个不对称单元含有一个Sj26单体。获得了一套完整的2.4?分辨率的自然衍射谱数据。©1995 Wiley-Liss公司
The 26‐kDa glutathioneS‐transferase fromSchistosoma japonica(Sj26), a potential antischistosomal vaccine antigen, has been crystallized in an unligated form. Sj26 was recombinantly produced inE. coliwithout using a glutathione affinity column to facilitate preparation of unligated enzyme. The recombinant protein contains all 218 residues of Sj261,2and an additional 13 residues linked to the C‐terminus. Crystals of recombinant Sj26 were obtained by the vapor diffusion method using ammonium sulfate as the precipitant at pH 5.6. The crystals belong to the hexagonal space groupP6322 with unit cell dimensionsa=b= 125.2 Å andc= 72.0 Å and contain one Sj26 monomer per asymmetric unit. A complete native diffraction data set has been obtained to 2.4 Å resolution. © 1995 Wiley‐Liss, Inc.
