Dobitchin PD, Kirillov SV, Noskin VA, Peshin NN. Correlation between biological activity of 30 S subunits of Escherichia coli ribosomes and their conformation changes revealed by optical mixing spectroscopy. Biophys Chem. 1983 Mar17(2):165-9. p.166 right column bottom paragraphPubMed ID6340749
|
| Method |
Spectral analysis of light scattered from solutions of 30 S subunits was performed by the method of regularization of the inverse spectral problem. |
| Comments |
Fig. 1 shows the dependence of the half-width
of the spectrum (F) vs. sin^2?/2 for active (a) and
inactivated (b) 30 S subunits. This dependence
yieids for the active particles a diffusion constant
D20,w=(1.83±0.10)x10^-7cm2/s and a hydrodynamical
diameter 235±12Å. |
