Structure and function of the acidic ribosomal stalk proteins.
The acidic L7/L12 (prokaryotes) and P1/P2 (eukaryotes) proteins are the only ribosomal components that occur in more than one, specifically four, copies in the translational machinery. These ribosomal proteins are the only ones that do not directly interact with ribosomal RNA but bind to the particles via a protein, L10 and P0, respectively. They constitute a morphologically distinct feature on...
متن کاملStructure function relationships in the ribosomal stalk proteins of archaebacteria.
The ribosomal L12 protein gene of Sulfolobus solfataricus (SsoL12) has been subcloned and overexpressed in Escherichia coli. Five protein L12 mutants were designed: two NH2-terminal and two COOH-terminal truncated mutants and one mutant lacking the highly charged part of the COOH-terminal region. The mutant protein genes were overexpressed in E. coli and the products purified. The amino acid co...
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 کاملModification of Yeast Ribosomal Proteins
Two-dimensional polyacrylamide-gel electrophoretic analysis of yeast ribosomal proteins uniformly labelled in vivo with [methyl-3H]methionine and [1-'4C]methionine revealed that four ribosomal proteins are methylated, i.e. proteins S31, S32, L15 and L41. Lysine and arginine appear to be the predominant acceptors of the methyl groups. The degree of methylation ranges from 0.09 to 0.20 methyl gro...
متن کاملIsolation 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...
