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...
متن کاملMitochondrial 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...
متن کاملStepwise Splitting of Ribosomal Proteins from Yeast Ribosomes by LiCl
Structural studies have revealed that the core of the ribosome structure is conserved among ribosomes of all kingdoms. Kingdom-specific ribosomal proteins (r-proteins) are located in peripheral parts of the ribosome. In this work, the interactions between rRNA and r-proteins of eukaryote Saccharomyces cerevisiae ribosome were investigated applying LiCl induced splitting and quantitative mass sp...
متن کاملProtein kinases CKI and CKII are implicated in modification of ribosomal proteins of the yeast Trichosporon cutaneum.
Phosphorylation of acidic ribosomal proteins P1/P2-P0 is a common phenomenon in eukaryotic organisms. It was found previously that in Trichosporon cutaneum, unlike in other yeast species, in addition to the two acidic ribosomal proteins, two other proteins of 15 kDa and 19 kDa of the small ribosomal subunit were phosphorylated. Here we describe two protein kinases: CKI and CKII, which are engag...
متن کاملHomologous 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 ...
