Kinetic proofreading at single molecular level: Aminoacylation of tRNA^{Ile} and the role of water as an editor [PDF]

open access: yes, 2013
Proofreading/editing in protein synthesis is essential for accurate translation of information from the genetic code. In this article we present a theoretical investigation of efficiency of a kinetic proofreading mechanism that employs hydrolysis of the ...

Akkermansia Muciniphila Alleviates Severe Acute Pancreatitis via Amuc1409‐Ube2k‐Foxp3 Axis in Regulatory T Cells

open access: yesAdvanced Science, EarlyView.
Akkermansia depletion correlates with acute pancreatitis (AP) severity. A. muciniphila and its protein Amuc_1409 mitigate pancreatic/systemic inflammation by expanding Tregs and IL‐10. Mechanistically, Amuc_1409 binds Ube2k, inhibiting Foxp3 ubiquitination to stabilize Treg differentiation and IL‐10 production, countering SAP‐induced SIRS/CARS ...

The Bipartite Structure of the tRNA m\u3csup\u3e1\u3c/sup\u3eA58 Methyltransferase from \u3cem\u3eS. cerevisiae\u3c/em\u3e is Conserved in Humans [PDF]

open access: yes, 2005
Among all types of RNA, tRNA is unique given that it possesses the largest assortment and abundance of modified nucleosides. The methylation at N1 of adenosine 58 is a conserved modification, occurring in bacterial, archaeal, and eukaryotic tRNAs. In the

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics

open access: yesAdvanced Science, EarlyView.
The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

tRNA 3\u27-amino-tailing for stable amino acid attachment. [PDF]

open access: yes, 2018
Amino acids are attached to the tRNA 3\u27-end as a prerequisite for entering the ribosome for protein synthesis. Amino acid attachment also gives tRNA access to nonribosomal cellular activities.

Impact of Virus‐Mediated Modifications in Bacterial Communities on the Accumulation of Soil Organic Carbon

open access: yesAdvanced Science, EarlyView.
This study illustrates the impact of viruses on carbon cycling in soils with different availabilities of carbon. In conditions of low carbon availability, viruses adopt a lysogenic lifestyle, integrate into the host genomes and facilitate the degradation of carbon.

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

open access: yesAdvanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed

Multiple Layers of Stress-Induced Regulation in tRNA Biology

open access: yesLife, 2016
tRNAs are the fundamental components of the translation machinery as they deliver amino acids to the ribosomes during protein synthesis. Beyond their essential function in translation, tRNAs also function in regulating gene expression, modulating ...
