Abstract
Sulfur particles were isolated from the purple sulfur photosynthetic bacterium, Chromatium vinosum strain D. The composition of these particles was determined to be 93% sulfur, 5% protein, and 0.6% lipid. Gel electrophoresis indicated the presence of a single protein species with a molecular weight of 13,500 daltons. From these results, the sulfur particle is postulated to be bounded by a membrane consisting entirely of protein.
摘要
从紫色硫光合细菌嗜硫色杆菌D菌株中分离出硫颗粒。经测定，这些颗粒的组成成分为93%的硫、5%的蛋白质和0.6%的脂质。凝胶电泳表明存在一种分子量为13500道尔顿的单一蛋白质。根据这些结果，推测硫颗粒由完全由蛋白质组成的膜包裹。
