  • Title: New low resolution model for 50S subunit of Escherichia coli ribosomes.
    Author: Stuhrmann HB, Haas J, Ibel K, Wolf B, Koch MH, Parfait R, Crichton RR.
    Journal: Proc Natl Acad Sci U S A; 1976 Jul; 73(7):2379-83. PubMed ID: 781676.
    Abstract:
    Neutron low angle scattering studies of the 50S subunit of E. coli ribosomes with the contrast variation method reveals large fluctuations in the scattering density. A region of relatively low scattering density, rich in proteins, surrounds an RNA-rich core of higher scattering density. The centers of mass of the RNA and protein parts of the 50S subunit are separated by a distance (20 A) that is considerably smaller than that reported in previous studies.
