Structure of Ribosomes [PDF]

open access: possibleCanadian Journal of Biochemistry, 1979
Ribosomes are multicomponent particles on which biosynthesis of proteins occurs in all organisms. The best known ribosome, namely that of Escherichia coli, consists of three RNAs and 53 different proteins. All proteins have been isolated and characterized by chemical, physical, and immunological methods. The primary sequences of 47 E.

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 on the Surface of Ribosomes

Science, 1963
Ribonuclease 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, 1982
The 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, 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 ...

Terbium binding to ribosomes and ribosomal RNA

Biochemistry, 1975
Terbium 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

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 ...

The ribosome revealed

Trends in Biochemical Sciences, 2005
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 mitochondrial ribosomes

Biochimie, 1991
Abstract Recent advances in the molecular and genetic studies of mitoribosomes especially on the molecular components of the mitoribosome in yeast Saccharomyces cerevisiae which have been investigated in detail in several laboratories, are reviewed.
