Egorov A, Atkinson G
NAR Genom Bioinform
. 2025 Feb;
7(1):lqaf009.
PMID: 40007724
Comparative genomic analysis often involves visualization of alignments of genomic loci. While several software tools are available for this task, ranging from Python and R libraries to stand-alone graphical user...

Sci Adv
. 2024 Nov;
10(46):eadr9624.
PMID: 39536105
Translation-targeting toxic small alarmone synthetases (toxSAS) are effectors of bacterial toxin-antitoxin systems that pyrophosphorylate the 3'-CCA end of transfer RNA (tRNA) to prevent aminoacylation. toxSAS are implicated in antiphage immunity:...

Nucleic Acids Res
. 2024 Jun;
52(16):9854-9866.
PMID: 38943426
Efficiency of protein synthesis on the ribosome is strongly affected by the amino acid composition of the assembled amino acid chain. Challenging sequences include proline-rich motifs as well as highly...

Dominguez-Molina L, Kurata T, Cepauskas A, Echemendia-Blanco D, Zedek S, Talavera-Perez A, et al.
Nat Chem Biol
. 2024 Jun;
21(2):182-192.
PMID: 38834893
Toxic small alarmone synthetase (toxSAS) enzymes constitute a family of bacterial effectors present in toxin-antitoxin and secretion systems. toxSASs act through either translation inhibition mediated by pyrophosphorylation of transfer RNA...

Mets T, Kurata T, Ernits K, Johansson M, Craig S, Evora G, et al.
Cell Host Microbe
. 2024 May;
32(7):1059-1073.e8.
PMID: 38821063
Toxin-antitoxins (TAs) are prokaryotic two-gene systems composed of a toxin neutralized by an antitoxin. Toxin-antitoxin-chaperone (TAC) systems additionally include a SecB-like chaperone that stabilizes the antitoxin by recognizing its chaperone...

Nucleic Acids Res
. 2024 May;
52(14):8483-8499.
PMID: 38811035
Ribosomes trapped on mRNAs during protein synthesis need to be rescued for the cell to survive. The most ubiquitous bacterial ribosome rescue pathway is trans-translation mediated by tmRNA and SmpB....

Aleksandrova E, Wu K, Tresco B, Syroegin E, Killeavy E, Balasanyants S, et al.
Nat Chem Biol
. 2024 Jan;
20(7):867-876.
PMID: 38238495
The bacterial ribosome is an essential drug target as many clinically important antibiotics bind and inhibit its functional centers. The catalytic peptidyl transferase center (PTC) is targeted by the broadest...

Mol Cell
. 2024 Jan;
84(4):715-726.e5.
PMID: 38183984
Rescuing stalled ribosomes often involves their splitting into subunits. In many bacteria, the resultant large subunits bearing peptidyl-tRNAs are processed by the ribosome-associated quality control (RQC) apparatus that extends the...
