Description

Neutron low angle scattering studies of the 50S subunit of Escherichia coli ribosomes using 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 centres of mass of the RNA and protein parts of the 50S subunit are separated by a distance that is considerably smaller than that reported in previous studies. (orig.)

Abstract (German)

Bei Neutronen-Kleinwinkelstreuungsuntersuchungen an der 50S-Untereinheit von Escherichia coli-Ribosomen nach dem Kontrastvariationsverfahren zeigen sich starke Schwankungen der Streudichte. Ein proteinreicher Bereich relativ geringer Streudichte umgibt einen RNS-reichen Kern hoeherer Streudichte. Die Entfernung zwischen den Massenzentren der RNS- und Proteinanteile der 50S-Untereinheit ist erheblich kleiner als in frueheren Berichten angegeben. (orig./AK)
