Thompson R, Carbaugh D, Nielsen J, Witt C, Faison E, Meganck R, et al.
Nat Chem Biol
. 2025 Feb;
PMID: 39939412
Biomolecules continually sample alternative conformations. Consequently, even the most energetically favored ground conformational state has a finite lifetime. Here, we show that, in addition to the three-dimensional (3D) structure, the...

Magn Reson (Gott)
. 2023 Oct;
2(2):715-731.
PMID: 37905209
In duplex DNA, Watson-Crick A-T and G-C base pairs (bp's) exist in dynamic equilibrium with an alternative Hoogsteen conformation, which is low in abundance and short-lived. Measuring how the Hoogsteen...

Proc Natl Acad Sci U S A
. 2022 Jun;
119(24):e2112496119.
PMID: 35671421
Thermodynamic preferences to form non-native conformations are crucial for understanding how nucleic acids fold and function. However, they are difficult to measure experimentally because this requires accurately determining the population...

Nat Commun
. 2021 Sep;
12(1):5201.
PMID: 34465779
N-methyladenosine (mA) is a post-transcriptional modification that controls gene expression by recruiting proteins to RNA sites. The modification also slows biochemical processes through mechanisms that are not understood. Using temperature-dependent...

J Phys Chem B
. 2021 Jul;
125(28):7613-7627.
PMID: 34236202
Measuring the strength of the hydrogen bonds between DNA base pairs is of vital importance for understanding how our genetic code is physically accessed and recognized in cells, particularly during...

Nat Commun
. 2020 Nov;
11(1):5531.
PMID: 33139729
Biomolecules form dynamic ensembles of many inter-converting conformations which are key for understanding how they fold and function. However, determining ensembles is challenging because the information required to specify atomic...

Nature
. 2020 Oct;
587(7833):291-296.
PMID: 33087930
Transcription factors recognize specific genomic sequences to regulate complex gene-expression programs. Although it is well-established that transcription factors bind to specific DNA sequences using a combination of base readout and...

PMID: 32459476
DNA bases can adopt energetically unfavorable tautomeric forms that enable the formation of Watson-Crick-like (WC-like) mispairs, which have been proposed to give rise to spontaneous mutations in DNA and misincorporation...
