Compilation of 5S rRNA and 5S rRNA gene sequences
This is an update for the 5S rRNA sequences of the BERLIN RNA DATABANK last published in 1990 (1). The new entry consists of 25 eubacterial and 2 eukaryotic 5S rRNA sequences and 10 plant 5S rRNA pseudogenes (Table 1). Thus the BERLIN RNA DATABANK contains as of February 1, 1991 the 5S rRNA sequences of 44 archaebacteria, 292 eubacteria, 20 plastids, 6 mitochondria, 321 eukaryotes and 21 eukary...
متن کاملrRNA mutants in the yeast peptidyltransferase center reveal allosteric information networks and mechanisms of drug resistance
To ensure accurate and rapid protein synthesis, nearby and distantly located functional regions of the ribosome must dynamically communicate and coordinate with one another through a series of information exchange networks. The ribosome is approximately 2/3 rRNA and information should pass mostly through this medium. Here, two viable mutants located in the peptidyltransferase center (PTC) of ye...
متن کاملThe "DEAD box" protein DbpA interacts specifically with the peptidyltransferase center in 23S rRNA.
The Escherichia coli DEAD (Asp-Glu-Ala-Asp) box protein DbpA is a putative RNA helicase and established RNA-dependent ATPase and is the only member of the DEAD box protein family for which a specific RNA substrate, bacterial 23S rRNA, has been identified. We have investigated the nature of this specificity in depth and have localized by deletion mutagenesis and PCR a single region of 93 bases (...
متن کامل5S rRNA Data Bank
In this paper we present the updated version of the compilation of 5S rRNA and 5S rDNA nucleotide sequences. It contains 1622 primary structures of 5S rRNAs and 5S rRNA genes from 888 species. These include 58 archaeal, 427 eubacterial, 34 plastid, nine mitochondrial and 1094 eukaryotic DNA or RNA nucleotide sequences. The sequence entries are divided according to the taxonomic position of the ...
متن کاملThe solution structure of the loop E region of the 5S rRNA from spinach chloroplasts.
A structure has been obtained for the loop E region of the 5S rRNA from Spinacia oleracia chloroplast ribosomes using residual dipolar coupling data as well as NOE, J coupling and chemical shift information. Even though the loop E sequence of this chloroplast 5S rRNA differs from that of Escherichia coli loop E at approximately 40% of its positions, its conformation is remarkably similar to tha...
