Abstract
A new crystal form of chicken cytosolic aspartate aminotransferase (EC 2.6.1.1) has been grown using a mixture of ammonium sulfate with ethanol as a precipitant. Crystals of the enzyme belong to the space group P 2(1)2(1)2(1) having the following unit cell dimensions: a = 62.38 A, b = 117.41 A, c = 124.34 A. There is one molecule of the enzyme in the asymmetric unit. The crystals diffract at 1.8 A resolution.
摘要
利用硫酸铵与乙醇的混合物作为沉淀剂，培养出了鸡胞质天冬氨酸转氨酶（EC 2.6.1.1）的一种新晶型。该酶晶体属于空间群P 2(1)2(1)2(1)，其晶胞参数如下：a = 62.38 Å，b = 117.41 Å，c = 124.34 Å。不对称单元中有一个酶分子。这些晶体的衍射分辨率为1.8 Å。
