Summary: The corrected sedimentation coefficients, expressed as (S20,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.
