Abstract

To clarify the intra- and inter-particle effects of magnesium ions onE. coli ribosomes we have performed measurements of light scattering intensity, index of refraction and small-angle neutron scattering on the 70S complex and 30S and 50S subunits with and without magnesium. The results indicate that magnesium has a specific intra-particle effecton the subunits as well as on the 70S complex. Besides, the distance distribution function shows that magnesium has an effect on the supra-ribosomal aggregation. The combination of these intra- and inter-particle effects completely hides, in the scattering experiments, any effect of magnesium on the degree of association of the two subunits into the 70S complex.
