Partial Denaturation of Double-Stranded DNA on Pristine Graphene under Physiological-like Conditions

open access: yesLiquids, 2023
Interactions between DNA and graphene are paramount for a wide range of applications, such as biosensing and nanoelectronics; nonetheless, the molecular details of such interactions remain largely unexplored.

Probing structural heterogeneities and fluctuations of nucleic acids and denatured proteins [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
We study protein and nucleic acid structure and dynamics using single-molecule FRET and alternating-laser excitation. Freely diffusing molecules are sorted into subpopulations based on single-molecule signals detected within 100 μs to 1 ms.

Development of an Interaction Assay between Single-Stranded Nucleic Acids Trapped with Silica Particles and Fluorescent Compounds

open access: yesJournal of Functional Biomaterials, 2012
Biopolymers are easily denatured by heating, a change in pH or chemical substances when they are immobilized on a substrate. To prevent denaturation of biopolymers, we developed a method to trap a polynucleotide on a substrate by hydrogen bonding using ...

Simplified Paper Format for Detecting HIV Drug Resistance in Clinical Specimens by Oligonucleotide Ligation. [PDF]

open access: yesPLoS ONE, 2016
Human immunodeficiency virus (HIV) is a chronic infection that can be managed by antiretroviral treatment (ART). However, periods of suboptimal viral suppression during lifelong ART can select for HIV drug resistant (DR) variants.

Novel Selenium-modified Nucleic Acids For Structural and Functional Studies [PDF]

open access: yes, 2015
Nucleic acids, as one of the most important macromolecules in living systems, play critical roles in storing, transferring, regulating genetic information, directing proteins synthesis, and catalysis. Understanding the structure of nucleic acid can bring

Hypoxanthine-Guanine Phosphoribosyltransferase/adenylate Kinase From Zobellia galactanivorans: A Bifunctional Catalyst for the Synthesis of Nucleoside-5′-Mono-, Di- and Triphosphates

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
In our search for novel biocatalysts for the synthesis of nucleic acid derivatives, we found a good candidate in a putative dual-domain hypoxanthine-guanine phosphoribosyltransferase (HGPRT)/adenylate kinase (AMPK) from Zobellia galactanivorans (ZgHGPRT ...

Effects of osmolytes and macromolecular crowders on stable GAAA tetraloops and their preference for a CG closing base pair [PDF]

open access: yesPeerJ, 2018
Osmolytes and macromolecular crowders have the potential to influence the stability of secondary structure motifs and alter preferences for conserved nucleic acid sequences in vivo.
