A Complete Mapping of the Proteins in the Small Ribosomal Subunit of <i>Escherichia coli</i>

Abstract

The relative positions of the centers of mass of the 21 proteins of the 30S ribosomal subunit from Escherichia coli have been determined by triangulation using neutron scattering data. The resulting map of the quaternary structure of the small ribosomal subunit is presented, and comparisons are made with structural data from other sources.
