Structural Model of the 50 S Subunit of Escherichia coli Ribosomes from Solution Scattering

摘要: The application of new methods small-angle scattering data interpretation to a contrast variation study the 50 S ribosomal subunit Escherichia coli in solution is described. experimental X-ray from with sucrose are analysed terms basic functions real and curves volume inaccessible regions inside this occupied mainly by RNA proteins obtained. From these models shape its RNA-rich core evaluated. These two shapes positioned so that their difference, which approximates proteins, produces curve good agreement protein moiety.
