[HTML][HTML] FID-Net: A versatile deep neural network architecture for NMR spectral reconstruction and virtual decoupling

G Karunanithy, DF Hansen - Journal of biomolecular NMR, 2021 - Springer
In recent years, the transformative potential of deep neural networks (DNNs) for analysing
and interpreting NMR data has clearly been recognised. However, most applications of DNNs …

Multiquantum chemical exchange saturation transfer NMR to quantify symmetrical exchange: Application to rotational dynamics of the guanidinium group in arginine …

G Karunanithy, J Reinstein… - The journal of physical …, 2020 - ACS Publications
Chemical exchange saturation transfer (CEST) NMR experiments have emerged as a powerful
tool for characterizing dynamics in proteins. We show here that the CEST approach can …

Virtual homonuclear decoupling in direct detection nuclear magnetic resonance experiments using deep neural networks

G Karunanithy, HW Mackenzie… - Journal of the American …, 2021 - ACS Publications
Nuclear magnetic resonance (NMR) experiments are frequently complicated by the
presence of homonuclear scalar couplings. For the growing body of biomolecular 13 C-detected …

Selective radical trifluoromethylation of native residues in proteins

M Imiołek, G Karunanithy, WL Ng… - Journal of the …, 2018 - ACS Publications
The incorporation of fluorine can not only significantly facilitate the study of proteins but also
potentially modulate their function. Though some biosynthetic methods allow global residue-…

Methodological advancements for characterising protein side chains by NMR spectroscopy

G Karunanithy, VK Shukla, DF Hansen - Current Opinion in Structural …, 2021 - Elsevier
The surface of proteins is covered by side chains of polar amino acids that are imperative
for modulating protein functionality through the formation of noncovalent intermolecular …

[HTML][HTML] Dynamic design: manipulation of millisecond timescale motions on the energy landscape of cyclophilin A

J Juárez-Jiménez, AA Gupta, G Karunanithy… - Chemical …, 2020 - pubs.rsc.org
Proteins need to interconvert between many conformations in order to function, many of
which are formed transiently, and sparsely populated. Particularly when the lifetimes of these …

[HTML][HTML] The anatomy of unfolding of Yfh1 is revealed by site-specific fold stability analysis measured by 2D NMR spectroscopy

R Puglisi, G Karunanithy, DF Hansen… - Communications …, 2021 - nature.com
Most techniques allow detection of protein unfolding either by following the behaviour of
single reporters or as an averaged all-or-none process. We recently added 2D NMR …

INDIANA: An in-cell diffusion method to characterize the size, abundance and permeability of cells

G Karunanithy, RJ Wheeler, LR Tear, NJ Farrer… - Journal of Magnetic …, 2019 - Elsevier
NMR and MRI diffusion experiments contain information describing the shape, size,
abundance, and membrane permeability of cells although extracting this information can be …

[HTML][HTML] Towards autonomous analysis of chemical exchange saturation transfer experiments using deep neural networks

G Karunanithy, T Yuwen, LE Kay… - Journal of Biomolecular …, 2022 - Springer
Macromolecules often exchange between functional states on timescales that can be accessed
with NMR spectroscopy and many NMR tools have been developed to characterise the …

Monitoring the Disassembly of Virus-like Particles by 19F-NMR

…, AAA Ajabali, G Karunanithy… - Journal of the …, 2017 - ACS Publications
Virus-like particles (VLPs) are stable protein cages derived from virus coats. They have been
used extensively as biomolecular platforms, eg, nanocarriers or vaccines, but a convenient …
