Quaternary Organization of the 30S Ribosomal Subunit of Escherichia Coli.
is the density distribution in the image; x, y are coordinates relative to its center of gravity; and p, q are integers; p + q is the order of the moment. By combining these moments, certain invariants can be formed which may be used to describe the image with increasing accuracy as the order of moments included increases (14). Instead of the images themselves, the profiles formed by its moment...
متن کاملPrecise determination of RNA-protein contact sites in the 50 S ribosomal subunit of Escherichia coli.
RNA-protein cross-linked complexes were isolated and purified to obtain precise data about RNA-protein contact sites in the 50 S ribosomal subunit of Escherichia coli. N-terminal microsequencing and matrix-assisted laser desorption ionization MS were used to identify the cross-linking sites at the amino acid and nucleotide levels. In this manner the following contact sites of five ribosomal pro...
متن کاملAsymmetry in the 50S ribosomal subunit of Escherichia coli.
A substantial separation of the centers of mass of the protein and RNA portions of the 50S ribosomal subunit has been achieved using neutron scattering. This separation reveals that the subunit has a protein-rich side, a finding which is inconsistent with many models proposed for the structure. By analyzing the variation of the radius of gyration of the subunit under conditions in which the con...
متن کاملIsotropic diffusion of the small ribosomal subunit in Escherichia coli
The ribosome is one of the most important macromolecular complexes in a living cell. We have tracked individual 30S ribosomal subunits in exponentially growing E. coli cells using threedimensional single-particle tracking, where the z -position is estimated using astigmatism. The 30S subunits are stochiometrically labeled with S2-mEos2 by replacing the rpsB gene in the E. coli chromosome by rps...
متن کاملA ribonucleoprotein core in the 50 S ribosomal subunit of Escherichia coli.
Many methods have been used for investigating the structural organisation of the ribosome. Although steady progress has been made in characterising both the RNA and protein regions that are accessible on the surface of the ribosome and the approximate locations of the RNA binding sites of the proteins, little is known about the internal organisation of proteins and RNA in the ribosomal subunits...
