Elucidation of the Translation Initiation Factor Interaction Network of Haloferax volcanii Reveals Coupling of Transcription and Translation in Haloarchaea

Frontiers in Microbiology, 2021
Translation is an important step in gene expression. Initiation of translation is rate-limiting, and it is phylogenetically more diverse than elongation or termination. Bacteria contain only three initiation factors. In stark contrast, eukaryotes contain

The kinetic mechanism of bacterial ribosome recycling. [PDF]

, 2017
Bacterial ribosome recycling requires breakdown of the post-termination complex (PoTC), comprising a messenger RNA (mRNA) and an uncharged transfer RNA (tRNA) cognate to the terminal mRNA codon bound to the 70S ribosome.

The PDB and the ribosome [PDF]

Journal of Biological Chemistry, 2021
This essay, which was written to commemorate the 50th anniversary of the Protein Data Bank, opens with some comments about the intentions of the scientists who pressed for its establishment and the nature of services it provides. It includes a brief account of the events that resulted in the determination of the crystal structure of the large ribosomal

Characterization of HicAB toxin-antitoxin module of Sinorhizobium meliloti

BMC Microbiology, 2019
Background Toxin-antitoxin (TA) systems are little genetic units generally composed of two genes encoding antitoxin and toxin. These systems are known to be involved in many functions that can lead to growth arrest and cell death.

General Approach for Introduction of Various Chemical Labels in Specific RNA Locations Based on Insertion of Amino Linkers

Molecules, 2013
Introduction of reporter groups at designed RNA sites is a widely accepted approach to gain information about the molecular environment of RNAs in their complexes with other biopolymers formed during various cellular processes.

The ribosome assembly gene network is controlled by the feedback regulation of transcription elongation [PDF]

, 2017
Ribosome assembly requires the concerted expression of hundreds of genes, which are transcribed by all three nuclear RNA polymerases. Transcription elongation involves dynamic interactions between RNA polymerases and chromatin.

Analyzing ribosome remodeling in health and disease [PDF]

PROTEOMICS (2020), 2020
regulation largely unexplored, in part due to methodological limitations. Indeed, we review evidence demonstrating that commonly used methods, such as transcriptomics, are inadequate because the variability in mRNAs coding for ribosomal proteins (RP) does not necessarily correspond to RP variability.

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.

Structure of the bacterial ribosome at 2 Å resolution

bioRxiv, 2020
Continuing advances in cryo-electron microscopy (cryo-EM) demonstrate the promise it holds for revealing biological structures at chemical resolution, in which noncovalent interactions, RNA and protein modifications, and solvation can be modeled ...
