Bacterial riboproteogenomics : the era of N-terminal proteoform existence revealed [PDF]

, 2020
With the rapid increase in the number of sequenced prokaryotic genomes, relying on automated gene annotation became a necessity. Multiple lines of evidence, however, suggest that current bacterial genome annotations may contain inconsistencies and are ...

Nascent Ribosomes [PDF]

Cell, 2001
The conversion of a ribosomal RNA transcript to a cytoplasmic ribosome requires hundreds of accessory RNA and protein factors. Two papers published recently in Molecular Cell provide first looks at the association of these processing factors with the intermediates in ribosome synthesis (Harnpicharnchai et al., 2001; Bassler et al., 2001).

Didemnin B and ternatin-4 differentially inhibit conformational changes in eEF1A required for aminoacyl-tRNA accommodation into mammalian ribosomes

eLife, 2022
Rapid and accurate mRNA translation requires efficient codon-dependent delivery of the correct aminoacyl-tRNA (aa-tRNA) to the ribosomal A site. In mammals, this fidelity-determining reaction is facilitated by the GTPase elongation factor-1 alpha (eEF1A),

Hepatitis C virus 3'UTR regulates viral translation through direct interactions with the host translation machinery. [PDF]

, 2013
The 3' untranslated region (3'UTR) of hepatitis C virus (HCV) messenger RNA stimulates viral translation by an undetermined mechanism. We identified a high affinity interaction, conserved among different HCV genotypes, between the HCV 3'UTR and the host ...

Ribosomal proteins: functions beyond the ribosome [PDF]

Journal of Molecular Cell Biology, 2015
Although ribosomal proteins are known for playing an essential role in ribosome assembly and protein translation, their ribosome-independent functions have also been greatly appreciated. Over the past decade, more than a dozen of ribosomal proteins have been found to activate the tumor suppressor p53 pathway in response to ribosomal stress. In addition,

Cotranslational folding of proteins on the ribosome.

, 2020
Many proteins in the cell fold cotranslationally within the restricted space of the polypeptide exit tunnel or at the surface of the ribosome. A growing body of evidence suggests that the ribosome can alter the folding trajectory in many different ways ...

HCV IRES manipulates the ribosome to promote the switch from translation initiation to elongation. [PDF]

, 2013
The internal ribosome entry site (IRES) of the hepatitis C virus (HCV) drives noncanonical initiation of protein synthesis necessary for viral replication.

Ribosome-omics of the human ribosome [PDF]

RNA, 2014
The torrent of RNA-seq data becoming available not only furnishes an overview of the entire transcriptome but also provides tools to focus on specific areas of interest. Our focus on the synthesis of ribosomes asked whether the abundance of mRNAs encoding ribosomal proteins (RPs) matched the equimolar need for the RPs in the assembly of ribosomes.

Kinetic modeling predicts a stimulatory role for ribosome collisions at elongation stall sites in bacteria

eLife, 2017
Ribosome stalling on mRNAs can decrease protein expression. To decipher ribosome kinetics at stall sites, we induced ribosome stalling at specific codons by starving the bacterium Escherichia coli for the cognate amino acid. We measured protein synthesis
