Protoplasma, 1972 The ribosomes of the naked flagellateDunaliella spec. which belongs to theVolvocales were isolated and characterized at different Mg2+-concentrations by isokinetic density sedimentation. 80 s ribosomes from the cytosol as well as 70 s ribosomes from the chloroplast are very sensitive against Mg2+-deprivation.

Canadian 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.

The structural basis of ribosome activity in peptide bond synthesis.
Science, 2000Using the atomic structures of the large ribosomal subunit from Haloarcula marismortui and its complexes with two substrate analogs, we establish that the ribosome is a ribozyme and address the catalytic properties of its all-RNA active site.

Annual Review of Biochemistry, 2019
Ribosomes, which synthesize the proteins of a cell, comprise ribosomal RNA and ribosomal proteins, which coassemble hierarchically during a process termed ribosome biogenesis.

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

Systematic Review of Plant Ribosome Heterogeneity and Specialization
Frontiers in Plant Science, 2020 Plants dedicate a high amount of energy and resources to the production of ribosomes. Historically, these multi-protein ribosome complexes have been considered static protein synthesis machines that are not subject to extensive regulation but only read ...

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.
