Location of ribosomal protein binding sites on 16S ribosomal RNA.
The distribution of ribosomal protein binding sites on the 16S ribosomal RNA molecule has been analyzed by limited ribonuclease hydrolysis of RNA-protein complexes, as well as by the interaction of individual proteins with RNA fragments purified from partial enzymatic digests. Of the six 30S subunit proteins known to interact directly with 16S RNA, proteins S4, S8, S15, S20, and, probably, S13 ...
متن کاملHow bacterial ribosomal protein L20 assembles with 23 S ribosomal RNA and its own messenger RNA.
In bacteria, the expression of ribosomal proteins is often feedback-regulated at the translational level by the binding of the protein to its own mRNA. This is the case for L20, which binds to two distinct sites of its mRNA that both resemble its binding site on 23 S rRNA. In the present work, we report an NMR analysis of the interaction between the C-terminal domain of L20 (L20C) and both its ...
متن کاملThe minimal eukaryotic ribosomal DNA units in the primitive red alga Cyanidioschyzon merolae.
Cyanidioschyzon merolae is a small unicellular red alga that is considered to belong to one of the most deeply branched taxa in the plant kingdom. Its genome size is estimated to be 16.5 Mbp, one of the smallest among free-living eukaryotes. In the nucleus containing this small genome, one nucleolus is clearly observed, but the molecular basis for the intranuclear structure including ribosomal ...
متن کاملFeedback regulation of ribosomal protein gene expression in Escherichia coli: structural homology of ribosomal RNA and ribosomal protein MRNA.
Certain ribosomal proteins (r proteins) in Escherichia coli, such as S4 and S7, function as feedback repressors in the regulation of r-protein synthesis. These proteins inhibit the translation of their own mRNA. The repressor r proteins so far identified are also known to bind specifically to rRNA at an initial stage in ribosome assembly. We have found structural homology between the S7 binding...
