A large 12S RNA fragment which constitutes the 5' two-thirds of 16S-RNA from the E. coli 30S subunit has been investigated by small-angle X-ray and neutron scattering. The results indicate that in reconstitution buffer the 12S-RNA fragment has a molecular weight of 270,000 +/- 20,000 and a radius of gyration of 7.1 nm. The scattering data are compatible with the RNA being folded into two major domains with the shapes of two adjacent, quite similar cylinders.
一个构成大肠杆菌30S亚基16S - RNA 5'三分之二的大12S RNA片段已通过小角X射线和中子散射进行了研究。结果表明,在重构缓冲液中,12S - RNA片段的分子量为270,000±20,000,回转半径为7.1纳米。散射数据与RNA折叠成两个主要结构域相符,这两个结构域的形状为两个相邻且非常相似的圆柱体。
