牛脾组织蛋白酶B用悬滴法提纯并结晶为与特异性抑制剂CA 074 [N-(1 -3-trans-propylcarbamoyloxirane-2-carbonyl)-1-isoleucyl-1-proline]的复合物。在50 m m-柠檬酸盐缓冲溶液(pH3.5)中得到的配合物晶体属四元晶系,空间群为P4.1(或P4.3),a= 73.06 A/cm,c= 141.59 A/cm。每个不对称单元有两个复合物分子,其堆积密度为3.37 × 10 - 3/Da,表明溶剂含量高,为63.5%。
Cathepsin B from bovine spleen has been purified and crystallized as a complex with a specific inhibitor CA074 [N-(l-3-trans-propylcarbamoyloxirane-2-carbonyl)-l-isoleucyl-l-proline], using the hanging-drop method. The complex crystals obtained from 50 m m-citrate buffer (pH 3· 5) belong to the tetragonal space group P4 1 (or P4 3) with a= 73· 06 A ̊ and c= 141· 59 A ̊, and diffract beyond 2· 2 Å resolution. There are two complex molecules per asymmetric unit giving a packing density of 3· 37 Å 3/Da and indicating a high solvent content of 63· 5%.
