title: Bombyx mori L. ribosomal proteins: resolution, nomenclature, molecular weights and in vivo phosphorylation.
abstract: Bombyx mori L. ribosomal proteins have been analyzed by four related two-dimensional polyacrylamide gel electrophoretic systems (Madjar et al. 1977a). In the small and large subunits are present 32 and 45 proteins, respectively, whose numbering is proposed. No significant differences in composition or migration could be detected between proteins in membrane-bound ribosomes and free ribosomes. The molecular weights of the proteins vary from 60,000 to less than 10,000. In vivo phosphorylation was investigated by labeling with 32P-orthophosphate. Autoradiograms of four two dimensional gels unambiguously show five labeled ribosomal proteins: S1, S7, L6, L29, and L40.
