Isolation of Eukaryotic Ribosomal Proteins
The proteins of the large subunit of rat liver ribosomes were separated into seven groups by stepwise elution from carboxymethylcellulose with LiCl at pH 6.5. Seventeen proteins (L4, L5, Li’, L9, Lll, L12, L13, L21, L22, L23, L26, L27, L30, L33, L35’, L37, and L39) were isolated from three of the groups (B60, D60, G60) by ion exchange chromatography on carboxymethylcellulose and by filtration t...

متن کاملThe primary structures of ribosomal proteins S14 and S16 from the archaebacterium Halobacterium marismortui. Comparison with eubacterial and eukaryotic ribosomal proteins.
The amino acid sequences of two ribosomal proteins, S14 and S16, from the archaebacterium Halobacterium marismortui have been determined. Sequence data were obtained by the manual and solid-phase sequencing of peptides derived from enzymatic digestions with trypsin, chymotrypsin, pepsin, and Staphylococcus aureus protease as well as by chemical cleavage with cyanogen bromide. Proteins S14 and S...
متن کاملRibosomal Proteins Orchestrate the Biogenesis of Eukaryotic Large Ribosomal Subunits in a Sequential Fashion
Ribosome biogenesis in eukaryotes involves the transcription, folding, and processing of ribosomal RNA (rRNA), as well as the concomitant assembly of ribosomal proteins. Several hundred trans-acting assembly factors also play a role in the complex process of ribosome biogenesis. Investigations of the construction of ribosomes have focused primarily on the roles of these assembly factors. Little...
متن کاملCoordinate regulation of the synthesis of eukaryotic ribosomal proteins.
We have developed a method of r the direct measurement, in eukaryotic cells, of the synthesis of ribosomal proteins, irrespective of the synthesis of ribosomes. In this way the synthesis of ribosomal proteins has been examined in mutant strains of Saccharomyces cerevisiae, which are unable to synthesize ribosomes under nonpermissive conditions. The results suggest that the synthesis of more tha...
