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 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.

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.

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.

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.

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 ).

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.

Ribosomal proteins and the conformation of ribosomal ribonucleic acid

Journal of Molecular Biology, 1971
Abstract Heat-denatured 16 s ribosomal RNA from Escherichia coli will combine with the total 30 s ribosomal proteins to form partially active 30 s ribosomes. The reconstitution process results in a change in the structure of the RNA, which can be demonstrated by chromatography on columns of methylated albuminkieselguhr.

Crystallization of Ribosomes, Ribosomal Subunits, and Individual Ribosomal Proteins

1991
There is interest in the three-dimensional structure of the ribosome since it is a unique multicomponent biological system responsible for the biosynthesis of protein in the cell. The exceedingly complex structure of ribosomes (for example, the Escherichia coli ribosome, the molecular weight of which is 2.15•106 Da, consists of three types of RNA and ...
