Abstract

The B800-820 peripheral light-harvesting complex, an integral membrane protein from Rhodopseudomonas acidophila strain 7050, has been crystallized in a form suitable for X-ray diffraction analysis. The crystals belong to space group R32 with hexagonal cell dimensions a = 117.20, c = 295.14 A (at 100 K). A complete 2.8 A resolution data set has been collected and a structure solution obtained using molecular-replacement methods.

摘要

嗜酸性红假单胞菌7050菌株的B800 - 820外周光捕获复合体是一种整合膜蛋白,已结晶成适合X射线衍射分析的形式。这些晶体属于空间群R32,六方晶胞尺寸为a = 117.20,c = 295.14 Å(在100 K时)。已收集到完整的2.8 Å分辨率数据集,并使用分子置换方法获得了结构解。
