Towards inferring nanopore sequencing ionic currents from nucleotide chemical structures

open access: yesNature Communications, 2021
Nanopore sequencing allows users to identify nucleotide sequence from ionic currents. Here, the authors use deep learning to facilitate the de novo identification of modified nucleotides, particularly methylated cytosine and guanine, from the measured ...

Novel riboswitch ligand analogs as selective inhibitors of guanine-related metabolic pathways. [PDF]

open access: yesPLoS Pathogens, 2010
Riboswitches are regulatory elements modulating gene expression in response to specific metabolite binding. It has been recently reported that riboswitch agonists may exhibit antimicrobial properties by binding to the riboswitch domain.

Structural Basis of SARS-CoV-2 Polymerase Inhibition by Favipiravir

open access: yesThe Innovation, 2021
Summary: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has developed into an unprecedented global pandemic. Nucleoside analogs, such as Remdesivir and Favipiravir, can serve as the first-line broad-spectrum antiviral drugs ...

Essential role of GTP in epinephrine stimulation of human fat cell adenylate cyclase

open access: yesJournal of Lipid Research, 1981
The activity of epinephrine-sensitive adenylate cyclase of human fat cell ghosts is markedly enhanced by the GTP analog 5'-guanylyl-imidodiphosphate (GMP-P(NH)P), but a similar effect of GTP itself has not been heretofore demonstrable.

Identification of discriminant features from stationary pattern of nucleotide bases and their application to essential gene classification

open access: yesFrontiers in Genetics, 2023
Introduction: Essential genes are essential for the survival of various species. These genes are a family linked to critical cellular activities for species survival.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

open access: yes, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Common Mitochondrial DNA Mutations Generated through DNA-Mediated Charge Transport [PDF]

open access: yes, 2009
Mutation sites that arise in human mitochondrial DNA as a result of oxidation by a rhodium photooxidant have been identified. HeLa cells were incubated with [Rh(phi)2bpy]Cl3 (phi is 9,10-phenanthrenequinone diimine), an intercalating photooxidant, to ...

Guanine nucleotides and acute renal failure [PDF]

open access: yesJournal of Clinical Investigation, 2001
Sustained ischemic and nephrotoxic acute renal failure (ARF) are characterized by overt damage to renal tubules, including cell necrosis. As a result, these processes have frequently been termed acute tubular necrosis, but this description has long been known to be misleading, as much of the tubule damage is sublethal, and the extent of necrotic cell ...

Guanine Nucleotide Exchange Assay Using Fluorescent MANT-GDP

open access: yesBio-Protocol, 2018
GTPases are molecular switches that cycle between the inactive GDP-bound state and the active GTP-bound state. GTPases exchange nucleotides either by its intrinsic nucleotide exchange or by interaction with guanine nucleotide exchange factors (GEFs ...
