The yeast ribosomal protein S7 and its genes.

Ribosomal protein S7 of Saccharomyces cerevisiae is encoded by two genes RPS7A and RPS7B. The sequence of each copy was determined; their coding regions differ in only 14 nucleotides, none of which leads to changes in the amino acid sequence. The predicted protein consists of 261 amino acids, making it the largest protein of the 40 S ribosomal subunit. It is highly basic near the NH2 terminus, ...

Ribosomal protein S7 from Escherichia coli uses the same determinants to bind 16S ribosomal RNA and its messenger RNA.

Ribosomal protein S7 from Escherichia coli binds to the lower half of the 3' major domain of 16S rRNA and initiates its folding. It also binds to its own mRNA, the str mRNA, and represses its translation. Using filter binding assays, we show in this study that the same mutations that interfere with S7 binding to 16S rRNA also weaken its affinity for its mRNA. This suggests that the same protein...

Assembly of the 30S ribosomal subunit: positioning ribosomal protein S13 in the S7 assembly branch.

Studies of Escherichia coli 30S ribosomal subunit assembly have revealed a hierarchical and cooperative association of ribosomal proteins with 16S ribosomal RNA; these results have been used to compile an in vitro 30S subunit assembly map. In single protein addition and omission studies, ribosomal protein S13 was shown to be dependent on the prior association of ribosomal protein S20 for bindin...

Functional substitution of mouse ribosomal protein L27' for yeast ribosomal protein L29 in yeast ribosomes.

A cDNA clone of mouse ribosomal protein L27' was shown previously to be 62% identical in amino acid residues to yeast ribosomal protein L29. The L27' cDNA was expressed in yeast to determine the ability of the mouse protein to substitute for yeast L29 in assembling a functional ribosome. In a yeast strain resistant to cycloheximide by virtue of a recessive mutation in the L29 protein, the murin...

Introns within Ribosomal Protein Genes Regulate the Production and Function of Yeast Ribosomes

In budding yeast, the most abundantly spliced pre-mRNAs encode ribosomal proteins (RPs). To investigate the contribution of splicing to ribosome production and function, we systematically eliminated introns from all RP genes to evaluate their impact on RNA expression, pre-rRNA processing, cell growth, and response to stress. The majority of introns were required for optimal cell fitness or grow...
