Molecular dynamics simulation study of the binding of purine bases to the aptamer domain of the guanine sensing riboswitch [PDF]

, 2009
Riboswitches are a novel class of genetic control elements that function through the direct interaction of small metabolite molecules with structured RNA elements.

Substrate Nucleotide-Determined Non-Templated Addition of Adenine by Taq DNA Polymerase: Implications for PCR-Based Genotyping and Cloning

BioTechniques, 1996
The Applied Biosystems PRISMTM fluorescence-based genotyping system as well as the Invitrogen TA Cloning® vector system are influenced by the tendency of Taq DNA polymerase to add an adenine nucleotide to the 3′ end of PCR products after extension ...

Transcription start site scanning and the requirement for ATP during transcription initiation by RNA polymerase II [PDF]

, 2016
Saccharomyces cerevisiae RNA polymerase (Pol) II locates transcription start sites (TSS) at TATA-containing promoters by scanning sequences downstream from the site of preinitiation complex formation, a process that involves the translocation of ...

Recent advances in experimental techniques to probe fast excited-state dynamics in biological molecules in the gas phase : dynamics in nucleotides, amino acids and beyond [PDF]

, 2013
In many chemical reactions, an activation barrier must be overcome before a chemical transformation can occur. As such, understanding the behaviour of molecules in energetically excited states is critical to understanding the chemical changes that these ...

Sulfonylation sites for adenine and its nucleosides/nucleotides

Journal of Pharmaceutical Analysis
Sulfonylation is extensively used to label DNA and RNA, assess their interactions, and quantify components including nucleobases and nucleosides/nucleotides although the sulfonylation sites remain controversial.

The hypoxic tissue microenvironment as a driver of mucosal inflammatory resolution

Frontiers in Immunology, 2023
On the backdrop of all acute inflammatory processes lies the activation of the resolution response. Recent years have witnessed an emerging interest in defining molecular factors that influence the resolution of inflammation.

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.
