Crystals of the aspartate aminotransferase from Escherichia coli (aspC gene product) have been examined by X-ray analysis. The crystals grow as elongated rectangular prisms, with the symmetry of space group C2221. Unit cell dimensions are a = 156 A, b = 87.6 A, c = 80.6 A and alpha = beta = gamma = 90 degrees. There is one protein subunit of molecular weight 43,600 per asymmetric unit.
通过X射线分析对来自大肠杆菌的天冬氨酸转氨酶（aspC基因产物）晶体进行了研究。晶体生长为细长的长方体，具有空间群C2221的对称性。晶胞尺寸为a = 156埃，b = 87.6埃，c = 80.6埃，α = β = γ = 90度。每个不对称单元中有一个分子量为43,600的蛋白质亚基。
