Translesion DNA Polymerases

11.9K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Battery Technology

Background:

  • Aqueous zinc-metal batteries (AZMBs) require stable Solid Electrolyte Interface (SEI) layers for optimal performance.
  • Current SEI fabrication methods can be inefficient or lack control over interfacial chemistry.

Purpose of the Study:

  • To develop a biomimetic strategy for in situ SEI layer fabrication in AZMBs.
  • To optimize the interfacial chemistry of zinc anodes using a novel SEI formation mechanism.
  • To enhance the charge storage performance and cycling stability of AZMBs.

Main Methods:

  • Introduced benzyltriethylammonium tetrafluoroborate (BT) into Zinc trifluoromethanesulfonate (Zn(OTf)2) electrolyte.
  • Utilized a biomimetic approach inspired by transfer RNA (tRNA) for SEI formation.
  • Investigated the interaction between BT cations and OTf- anions to promote SEI layer decomposition on the Zn anode.

Main Results:

  • Achieved a robust SEI layer formation during the Zn2+ plating process.
  • Zn‖Zn symmetric cells demonstrated high cumulative capacity (7 Ah cm-2) and stable operation (>3600 h).
  • Zn-Br2 full batteries showed excellent capacity retention (97.4% after 2000 cycles) and long lifespan (>1500 cycles).

Conclusions:

  • The biomimetic SEI fabrication strategy significantly improves interfacial stability in AZMBs.
  • This method offers a promising pathway for developing high-performance and long-lasting AZMBs.
  • The study highlights the potential of bio-inspired designs in advanced battery technologies.
