Homologous ribosomal proteins in bacteria, yeast, and humans.

Homologous ribosomal proteins in bacteria, yeast, and humans.

We describe sequences of two human ribosomal proteins, S14 and S17, and messenger RNAs that encode them. cDNAs were used as molecular hybridization probes to recognize complementary genes in rodent, Drosophila, and yeast chromosomal DNAs. Human ribosomal protein sequences are compared to analogous Chinese hamster, yeast, and bacterial genes. Our observations suggest that some ribosomal protein ...

Modification 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...

Ribosomal Proteins from Chloroplasts, Bacteria, and Eucaryotes

Mitochondrial ribosomal proteins (MRPs) of yeast.

Mitochondrial ribosomal proteins (MRPs) are the counterparts in that organelle of the cytoplasmic ribosomal proteins in the host. Although the MRPs fulfil similar functions in protein biosynthesis, they are distinct in number, features and primary structures from the latter. Most progress in the eludication of the properties of individual MRPs, and in the characterization of the corresponding g...

The 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...
