Archaeal rRNA operons

Trends in Biochemical Sciences, 1991
Ribosomal RNA (rRNA) operons of the archaea reflect both the unity and the diversity of this third primary taxon. They have proven to be a rich source of both molecular biological and phylogenetic information.

Upstream binding factor-dependent and pre-rRNA transcription-independent association of pre-rRNA processing factors with rRNA gene

Biochemical and Biophysical Research Communications, 2014
The nucleolus is the ribosome biogenesis center. The nucleolar structure is disrupted upon entry into mitosis and is formed in early G1 phase. To understand the molecular mechanisms of nucleolar assembly and disassembly, we have studied the mechanism of association between factors involved in pre-ribosome RNA (rRNA) processing and rRNA gene chromatin ...

5S rRNA and ribosome

Biochemistry (Moscow), 2011
5S rRNA is an integral component of the ribosome of all living organisms. It is known that the ribosome without 5S rRNA is functionally inactive. However, the question about the specific role of this RNA in functioning of the translation apparatus is still open.

Glucocorticoid regulation of rRNA synthesis

Molecular and Cellular Biochemistry, 1991
Glucocorticoids inhibit transcription of the genes encoding rRNA (rDNA) in P1798 lymphoma cells. This is due to a decrease in the amount or activity of a transcription factor, called TFIC. TFIC has been purified to apparent homogeneity and the properties of this protein have been investigated in detail. TFIC is tightly associated with RNA polymerase I.

rRNA Methylation and Antibiotic Resistance

Biochemistry (Moscow), 2020
Methylation of nucleotides in rRNA is one of the basic mechanisms of bacterial resistance to protein synthesis inhibitors. The genes for corresponding methyltransferases have been found in producer strains and clinical isolates of pathogenic bacteria. In some cases, rRNA methylation by housekeeping enzymes is, on the contrary, required for the action ...
