Sedimentation Coefficients of Yeast Ribosomes De Ley, J.,, 37, 153-156 (1964), doi = https://doi.org/10.1099/00221287-37-1-153, publicationName = Microbiology Society, issn = 1350-0872, abstract= Summary: The corrected sedimentation coefficients, expressed as (S 20,w)0, of ribosomes from nine different yeasts, representing a wide taxonomic range, were found to be 51·5 ± 2·4, 68·6 ± 3·3 and 86·7 ± 2·9 x 10−13 sec. Very small quantities of a faster (approximately 128 x 10−13 sec.) and a slower particle were sometimes detected. Yeast ribosomes have thus sedimentation coefficients which are distinctly different from bacterial ribosomes., language=, type=
