Ribosomes and ribosomal RNA as chaperones for folding of proteins
Folding and Design, 1997 Provocative recent reports indicate that the large subunits of either prokaryotic or eukaryotic ribosomes have the capacity to promote refolding of denatured enzymes.Salt-washed Escherichia coli ribosomes are shown to promote refolding of denatured rhodanese.

Transcription-translation coupling: direct interactions of RNA polymerase with ribosomes and ribosomal subunits. [PDF]
, 2017 In prokaryotes, RNA polymerase and ribosomes can bind concurrently to the same RNA transcript, leading to the functional coupling of transcription and translation.

Protein synthesis by single ribosomes [PDF]
RNA, 2003 The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Interaction between the assembly of the ribosomal subunits: Disruption of 40S ribosomal assembly causes accumulation of extra-ribosomal 60S ribosomal protein uL18/L5. [PDF]
PLoS ONE, 2020 Inhibition of the synthesis of an essential ribosomal protein (r-protein) abrogates the assembly of its cognate subunit, while assembly of the other subunit continues.

Genome landscapes and bacteriophage codon usage [PDF]
, 2007 Across all kingdoms of biological life, protein-coding genes exhibit unequal usage of synonmous codons. Although alternative theories abound, translational selection has been accepted as an important mechanism that shapes the patterns of codon usage in ...

The social life of ribosomal proteins [PDF]
The FEBS Journal, 2005 Ribosomal proteins hold a unique position in biology because their function is so closely tied to the large rRNAs of the ribosomes in all kingdoms of life. Following the determination of the complete crystal structures of both the large and small ribosomal subunits from bacteria, the functional role of the proteins has often been overlooked when ...

Placeholder factors in ribosome biogenesis: please, pave my way
Microbial Cell, 2017 The synthesis of cytoplasmic eukaryotic ribosomes is an extraordinarily energy-demanding cellular activity that occurs progressively from the nucleolus to the cytoplasm.

Extraribosomal Functions of Cytosolic Ribosomal Proteins in Plants
Frontiers in Plant Science, 2021 Ribosomes are basic translational machines in all living cells. The plant cytosolic ribosome is composed of four rRNAs and approximately 81 ribosomal proteins (RPs). In addition to the fundamental functions of RPs in the messenger RNA decoding process as

Quantifying the benefit of a proteome reserve in fluctuating environments. [PDF]
, 2017 The overexpression of proteins is a major burden for fast-growing bacteria. Paradoxically, recent characterization of the proteome of Escherichia coli found many proteins expressed in excess of what appears to be optimal for exponential growth.
