Guanine quantum defects in carbon nanotubes for biosensing [PDF]

open access: yes, 2023
Fluorescent single wall carbon nanotubes (SWCNTs) are used as nanoscale biosensors in diverse applications. Selectivity is built in by non-covalent functionalization with polymers such as DNA.

The Two Faces of the Guanyl Radical: Molecular Context and Behavior

open access: yesMolecules, 2021
The guanyl radical or neutral guanine radical G(-H)• results from the loss of a hydrogen atom (H•) or an electron/proton (e–/H+) couple from the guanine structures (G). The guanyl radical exists in two tautomeric forms.

Substitutional Sodium Doping on Tungsten Ditelluride: A First-principles Study

open access: yesBibechana, 2022
Methylation at O6 atom of guanine is a type of DNA damage which can cause a cancer. This damage at O6 atom of guanine in a DNA can be transferred to SG atom of cysteine in O6-alkylguanine-DNA alkyltransferase (AGT).

NupR Responding to Multiple Signals Is a Nucleoside Permease Regulator in Bacillus thuringiensis BMB171

open access: yesMicrobiology Spectrum, 2022
Nucleoside transport is essential for maintaining intracellular nucleoside and nucleobase homeostasis for living cells. Here, we identified an uncharacterized GntR/HutC family transcriptional regulator, NagR2, renamed NupR (nucleoside permease regulator),
