Ribosomal RNA on the Surface of Ribosomes
Science, 1963Ribonuclease from pancreas releases nucleotide from Escherichia coli ribosomes while not altering significantly the base composition of the total ribosomal RNA. Ribonuclease hydrolyzes ribsomal RNA without destroying the structure of 70 S or 30 S and 50 S

Structure of ribosomes and ribosomal subunits of Drosophila
Molecular and General Genetics MGG, 1982The ultrastructure of Drosophila melanogaster cytoplasmic ribosomal subunits and monomers have been examined by electron microscopy. The Drosophila ribosomal structures are compared to those determined for other eucaryotes and E. coli. Negatively contrasted images of 60S subunits are seen in the most frequent view to be approximately round particles ...

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 ...

Terbium binding to ribosomes and ribosomal RNA
Biochemistry, 1975Terbium binding to rat liver ribosomes and ribosomal RNA (rRNA) was examined by equilibrium dialysis and fluorescence spectroscopy. Upon binding to ribosomes and rRNA, the enhancement of terbium fluorescence emission at both 488 and 541 nm was dependent only upon the amount of bound terbium and independent of ionic strength.

Crystallization of Ribosomes, Ribosomal Subunits, and Individual Ribosomal Proteins
1991There 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 ...

Fifty years is a long time. In 1955 – the year IUB (later renamed IUBMB) was established – it was known that protein synthesis is associated with ribonucleoprotein particles, which are abundant in cytoplasm, and that the small RNAs – now called tRNAs – are also involved, but no one knew what a ‘ribosome’ was because the word had not yet been coined [1].

The ribosome is a large multifunctional complex composed of both RNA and proteins. Biophysical methods are yielding low-resolution structures of the overall architecture of ribosomes, and high-resolution structures of individual proteins and segments of rRNA.

Ribosomes are fundamental components of the cell that are essential for its growth and proliferation. It is hard to imagine that such a fundamental physiological machinery, as ribosomes, does not participate in cancer biology. However, surprisingly, there is a lack of studies towards the role of ribosomal alterations in cancer. Here, we will attempt to
