Ribosomal RNA and ribosomal proteins in corynebacteria

Journal of Biotechnology, 2003
Ribosomal RNAs (rRNAs) (16S, 23S, 5S) encoded by the rrn operons and ribosomal proteins play a very important role in the formation of ribosomes and in the control of translation. Five copies of the rrn operon were reported by hybridization studies in Brevibacterium (Corynebacterium) lactofermentum but the genome sequence of Corynebacterium glutamicum ...

Ribosomal Proteins in the Spotlight

Critical Reviews in Biochemistry and Molecular Biology, 2005
The assignment of specific ribosomal functions to individual ribosomal proteins is difficult due to the enormous cooperativity of the ribosome; however, important roles for distinct ribosomal proteins are becoming evident. Although rRNA has a major role in certain aspects of ribosomal function, such as decoding and peptidyl-transferase activity ...

Protein folding on the ribosome

Current Opinion in Structural Biology, 2010
In living systems, polypeptide chains are synthesised on ribosomes, molecular machines composed of over 50 protein and nucleic acid molecules. As nascent chains emerge from the ribosomal exit tunnel and into the cellular environment, the majority must fold into specific structures in order to function.

Ribosomal proteins in halobacteria

Canadian Journal of Microbiology, 1989
The amino acid sequences of 16 ribosomal proteins from archaebacterium Halobacterium marismortui have been determined by a direct protein chemical method. In addition, amino acid sequences of three proteins, S11, S18, and L25, have been established by DNA sequencing of their genes as well as by protein sequencing.

Ribosome-inactivating proteins

Toxicon, 1997
Abstract Ribosome-inactivating proteins (RIPs, review by Barbieri et a/. 1993) are a class of proteins present in various tissues of several plants which inactivate mammalian ribosomes and, with less activity and to variable extent, plant, fungal, and bacterial ribosomes. They are enzymes, N-glycosidases, which release adenine from rRNA.

Ribosomal RNA: the message or matrix for ribosomal proteins

Canadian Journal of Biochemistry, 1976
The known nucleotide sequence of Escherichia coli 16S ribosomal RNA has been converted to amino acid sequences in all possible ways, and compared to known ribosomal protein sequences. The degree of similarity is precisely what one would expect by chance alone, providing additional evidence that ribosomal proteins cannot be coded for by ribosomal RNA.

The role of ribosomal protein for the binding of dihydrostreptomycin to ribosomes

Biochemical and Biophysical Research Communications, 1968
Abstract Although the lethal action of streptomycin (SM) may not be related to its effect on the protein biosynthesis, it appears clear that SM influences ribosomal function through inhibition or miscoding ( Davies et al. , 1964 ). The target of SM action is apparently 30S ribosomal subunits ( Cox et al. , 1962 ).

Ribosomal protein paralogues in ribosome specialization

Philosophical Transactions of the Royal Society B: Biological Sciences
Ribosomes are macromolecular complexes responsible for protein synthesis, comprising ribosomal proteins (RPs) and ribosomal RNA. While most RPs are present as single copies in higher eukaryotes, a handful of them have paralogues that emerged through duplication events.

The synthesis of ribosomal protein

Journal of Theoretical Biology, 1965
Abstract The hypothesis that nascent R-RNA associated with neosomes forms the unit responsible for the synthesis of ribosomal protein leads to a number of self-consistent relationships. The RNA of a 70 s ribosome is long enough to act as template for six molecules of ribosomal protein.

Ribosomes, ribosomal subunits and ribosomal proteins of Lactococcus lactis IL1403

Biochimie, 1992
Abstract The preparation of ribosomes and ribosomal subunits of Lactococcus lactis and the characterization of the proteins of the subunits by one- and two-dimensional polyacrylamide gel electrophoresis and ion exchange chromatography are described.
