Isolation of seventeen proteins and amino-terminal amino acid sequences of eight proteins from cytoplasmic ribosomes of yeast.
Seventeen ribosomal proteins of Saccharomyces cerevisiae were isolated from small ribosomal subunits and disodium ethylenediaminetetraacetate treated 80S ribosomes by chromatography on a column of carboxymethylcellulose and/or by filtration through Sephacryl S-200. The isolated proteins are YS4, YS7, YS8, YS9, YS10, YS12, YS14, YS18, YS23, YS29, YL11, YL13, YL16, YL17, YL22, YL38, and YL40 [nomenclature according to Otaka & Osawa (1981) [Otaka, E., & Osawa, S. (1981) Mol. Gen. Genet. 181, 176-182]]. The purification procedures and the amino acid compositions of these proteins are presented. Amino-terminal amino acid sequences of YS4, YS6, YS11, YS15, YS16, YS22, YL10, and YL31 have been determined and compared with those from rat liver [Wittmann-Liebold, B., Geissler, A. W., Lin, A., & Wool, I. G. (1979) J. Supramol. Struct. 12, 425-433] and Halobacterium cutirubrum [Matheson, A. T., Möller, W., Amons, R., & Yaguchi, M.
