Acetylation of ribosomal proteins. I. Characterization and properties of rat liver ribosomal proteins.
Rat liver ribosomes have been acetylated both in vivo and in vitro. The in vivo acetylation of ribosomes occurred within 5 min of the administration of t3H]acetate, and 70 to 80% of the incorporated radioactivity remained in the ribosomal proteins after removal of RNA with urea-LiCl. Following treatment of the acetylated ribosomai proteins with ethanol-ether, RNase, and 0.5 M KCl, to remove pos...
متن کاملEvolutionary microdivergence of chick and rat liver ribosomal proteins.
We have set out to establish a nomenclature for ribosomal proteins which transcends, as far as is possible, the species from which the ribosomes were isolated. Initally, we identified individual proteins of rat liver by two-dimensional polyacrylamide gel electrophoresis and comparison with the classification system established by others (Sherton, C.C., and Wool, I.G. (1972) J. Biol. Chem. 247, ...
متن کاملAcetylation of Ribosomal Proteins in Regenerating Rat Liver
It has been shown that rat liver ribosomal proteins can be acetylated both in viuo and in vitro (Liew & Gornall, 1973). After purification of the ribosomal proteins to remove any possible contamination by lipids, nucleotides and cytoplasmic protein, the radioactivity still remained in these proteins. When the [’Hlacetate-labelled ribosomal proteins were hydrolysed in strong acid at 110°C overni...
متن کاملThe primary structure of rat liver ribosomal protein L37. Homology with yeast and bacterial ribosomal proteins.
The covalent structure of the rat liver 60 S ribosomal subunit protein L37 was determined. Twenty-four tryptic peptides were purified and the sequence of each was established; they accounted for all 111 residues of L37. The sequence of the first 30 residues of L37, obtained previously by automated Edman degradation of the intact protein, provided the alignment of the first 9 tryptic peptides. T...
متن کاملPhosphorylation of ribosomal proteins in hamster fibroblasts infected with pseudorabies virus or herpes simplex virus.
In BHK cells infected with pseudorabies virus, there was a substantial increase in the phosphorylation of ribosomal protein S6. This increase occurred between 2 and 4 h after infection and persisted at least until 9 h. We estimated that in mock-infected cells S6 contained, on an average, one phosphate group per protein chain, whereas in infected cells this rose to between four and five phosphat...
