Abstract
An orthorhombic crystal form (P2(1)2(1)2(1)) of the reaction center from the photosynthetic bacterium Rhodopseudomonas sphaeroides R-26 has been characterized. The crystals were grown from polyethylene glycol; the unit cell dimensions are a = 142.2 A, b = 139.6 A, and c = 78.7 A; and they contain one reaction center in each crystallographic asymmetric unit. The crystals diffract to at least 3.0 A resolution, and are suitable for detailed structural studies.
摘要
已对光合细菌球形红假单胞菌R-26反应中心的正交晶型（P2(1)2(1)2(1)）进行了表征。晶体由聚乙二醇生长而成；晶胞尺寸为a = 142.2 Å，b = 139.6 Å，c = 78.7 Å；每个晶体学不对称单元中含有一个反应中心。这些晶体的衍射分辨率至少为3.0 Å，适用于详细的结构研究。
