Adeno‐associated virus serotype 2 capsid variants for improved liver‐directed gene therapy

open access: yesHepatology, EarlyView., 2022
Abstract Background and Aims Current liver‐directed gene therapies look for adeno‐associated virus (AAV) vectors with improved efficacy. With this background, capsid engineering is explored. Whereas shuffled capsid library screenings have resulted in potent liver targeting variants with one first vector in human clinical trials, modifying natural ...

Structure and mechanism of human DNA polymerase η [PDF]

open access: yes, 2010
The variant form of the human syndrome xeroderma pigmentosum (XPV) is caused by a deficiency in DNA polymerase eta (Pol eta), a DNA polymerase that enables replication through ultraviolet-induced pyrimidine dimers.

Distinct mechanisms of DNA sensing based on N-doped carbon nanotubes with enhanced conductance and chemical selectivity [PDF]

open access: yesSmall 10, 774 (2014), 2012
Carrying out first-principles calculations, we study N-doped capped carbon nanotube (CNT) electrodes applied to DNA sequencing. While we obtain for the face-on nucleobase junction configurations a conventional conductance ordering where the largest signal results from guanine according to its high highest occupied molecular orbital (HOMO) level, we ...

An archaeal family-B DNA polymerase variant able to replicate past DNA damage: occurrence of replicative and translesion synthesis polymerases within the B family [PDF]

open access: yes, 2014
A mutant of the high fidelity family-B DNA polymerase from the archaeon Thermococcus gorgonarius (Tgo-Pol), able to replicate past DNA lesions, is described.

Cyclobutane Thymine Photodimerization Mechanism Revealed by Nonadiabatic Molecular Dynamics.

open access: yesJournal of the American Chemical Society, 2016
The formation of cyclobutane thymine dimers is one of the most important DNA carcinogenic photolesions induced by ultraviolet irradiation. The long debated question whether thymine dimerization after direct light excitation involves singlet or triplet ...

Predicting the effects of basepair mutations in DNA-protein complexes by thermodynamic integration [PDF]

open access: yes, 2011
Thermodynamically rigorous free energy methods in principle allow the exact computation of binding free energies in biological systems. Here, we use thermodynamic integration together with molecular dynamics simulations of a DNA-protein complex to ...

Platinum(II)–dithiocarbamate complexes with phosphines: Synthesis, characterization and precursor for Pt nanoparticles using ultrasound assisted method [PDF]

open access: yesE3S Web of Conferences
The reaction between Na2[PtCl4] and thymine bisdithiocarbamate (tdtc) in a 2:1 molar ratio (Metal:Ligand) produced a square planar complex called [Pt(tdtc)2]n (1).

Phenotypic and genotypic characterisation of thymine auxotrophy in Escherichia coli isolated from a patient with recurrent bloodstream infection.

open access: yesPLoS ONE, 2022
IntroductionThymine auxotrophic in vitro mutants of Escherichia coli were first reported in the mid-20th century. Later, thymine-dependent clinical strains of E. coli as well as other Enterobacterales, Enterococcus faecalis and Staphylococcus aureus have

Why Replacing Different Oxygens of Thymine with Sulfur Causes Distinct Absorption and Intersystem Crossing.

open access: yesJournal of Physical Chemistry A, 2016
Recent experiments replacing oxygen atoms by sulfur in thymine have revealed that absorption and intersystem crossing properties of these derivatives are strongly dependent on the position and number of the substitutions, affecting their potential ...

Base pair opening within B-DNA: free energy pathways for GC and AT pairs from umbrella sampling simulations. [PDF]

open access: yes, 2003
The conformational pathways and the free energy variations for base opening into the major and minor grooves of a B-DNA duplex are studied using umbrella sampling molecular dynamics simulations. We compare both GC and AT base pair opening within a double-
