Ribosomal RNA and ribosomal proteins in corynebacteria
Journal of Biotechnology, 2003Ribosomal 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, 2005The 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, 2010In 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, 1989The 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, 1997Abstract 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.

Regulation and function of ribosomal protein S6 kinase (S6K) within mTOR signalling networks.
Biochemical Journal, 2012The ribosomal protein S6K (S6 kinase) represents an extensively studied effector of the TORC1 [TOR (target of rapamycin) complex 1], which possesses important yet incompletely defined roles in cellular and organismal physiology.

The role of ribosomal protein for the binding of dihydrostreptomycin to ribosomes
Biochemical and Biophysical Research Communications, 1968Abstract 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 ).
