Ribo-T is an engineered ribosome whose small and large subunits are tethered together by linking 16S rRNA and 23S rRNA in a single molecule. Although Ribo-T can support cell proliferation in the absence of wild type ribosomes, Ribo-T cells grow slower th
The ribosome particle is composed of two subunits, the sedimentation coefficients of which are 30 S and 50 S, respectively, and when the magnesium concentration is reduced to less than 0.5 mM by dialysis or with the use of a molecular sieve, the particle dissociates into its subunits. ...

摘要: 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.
Intrans-translation transfer messenger RNA (tmRNA) and small protein B (SmpB) rescue ribosomes stalled on truncated or in other ways problematic mRNAs. Smp... Ivanova,N. - 《Nucleic Acids Research》 被引量: 65发表: 2005年 Specific association of two homologous DNA-binding proteins to the nati...
aThe ribosome is a molecular machine that unites the mRNA with the appropriate tRNAs and then links the together into a chain. Prokaryotic ribosomes consist of two subunits called the 30S and 50S, which combine to form a functional 70S ribosome. 核糖体是与适当的tRNAs团结mRNA一起然后连接入链子...
我们需要知道具体问题和每一个地区有关。 [translate] aMoreover, the ribosomes in animal mitochondria are 28S and 39S in size, closer to the 30Sand 50Ssubunits of bacteria. 而且,核糖体在动物线粒体中是28S和39S在大小,离30Sand细菌50Ssubunits较近。 [translate] ...
The problem of establishing homogeneity for a complicated structure like a ribosome is not easily solved. Perhaps, such a concept should be irrelevant. The subunits of eukaryotic cytoplasmic ribosomes, in their “active” state, seem to behave more like supramolecular complexes than simple ribonucleopr...
Mutations at seven recombinationally distinct chloroplast loci confer antibiotic resistance on chloroplast ribosomes of the green alga Chlamydomonas reinhardtii. Assays of polynucleotide-directed amino acid incorporation by ribosomes reconstituted from mutant and wild type subunits demonstrate that streptomycin, ...
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...
