摘要以硫酸铵为沉淀剂，制备了牛神经physinⅱs-甲基- cys - tyr - ph - nh2配合物。晶体为正交晶系，空间群为I222或i21 12 12 1，空间群a= 124.9 a, b= 66.9 a, c= 155.1 a。晶体的衍射分辨率至少为3.0 Å。以每个非对称单元1个神经物理素四聚体为基础，计算出溶剂含量为69%时的马修斯系数为3·92。
Abstract A bovine neurophysin II S-methyl-Cys-Tyr-Phe-NH 2 complex has been crystallized using ammonium sulfate as the precipitating agent. The crystals are orthorhombic, the space group is either I222 or I2 1 2 1 2 1 with a= 124· 9 A ̊, b= 69· 6 A ̊ and c= 151· 5 A ̊. The crystals diffract to at least 3· 0 Å resolution. Based on one neurophysin tetramer per asymmetric unit, the Matthews coefficient is calculated to be 3· 92 with a solvent content of 69%.
