Discovery of multiple hidden allosteric sites by combining Markov state models and experiments

GR Bowman, ER Bolin, KM Hart… - Proceedings of the …, 2015 - National Acad Sciences
The discovery of drug-like molecules that bind pockets in proteins that are not present in
crystallographic structures yet exert allosteric control over activity has generated great interest in …

[HTML][HTML] Modelling proteins' hidden conformations to predict antibiotic resistance

KM Hart, CMW Ho, S Dutta, ML Gross… - Nature …, 2016 - nature.com
TEM β-lactamase confers bacteria with resistance to many antibiotics and rapidly evolves
activity against new drugs. However, functional changes are not easily explained by …

[HTML][HTML] Thermodynamic system drift in protein evolution

KM Hart, MJ Harms, BH Schmidt, C Elya… - PLoS …, 2014 - journals.plos.org
Proteins from thermophiles are generally more thermostable than their mesophilic homologs,
but little is known about the evolutionary process driving these differences. Here we …

Cleavable hydrophilic linker for one-bead-one-compound sequencing of oligomer libraries by tandem mass spectrometry

…, KM Hart, KM Brinner, M Tjandra… - Journal of …, 2006 - ACS Publications
We have developed a method for the rapid and unambiguous identification of sequences of
hit compounds from one-bead-one-compound combinatorial libraries of peptide and peptoid …

Prediction of new stabilizing mutations based on mechanistic insights from Markov state models

MI Zimmerman, KM Hart, CA Sibbald… - ACS central …, 2017 - ACS Publications
Protein stabilization is fundamental to enzyme function and evolution, yet understanding the
determinants of a protein’s stability remains a challenge. This is largely due to a shortage of …

[HTML][HTML] Designing small molecules to target cryptic pockets yields both positive and negative allosteric modulators

KM Hart, KE Moeder, CMW Ho, MI Zimmerman… - PloS one, 2017 - journals.plos.org
Allosteric drugs, which bind to proteins in regions other than their main ligand-binding or
active sites, make it possible to target proteins considered “undruggable” and to develop new …

[PDF][PDF] Cooperative changes in solvent exposure identify cryptic pockets, switches, and allosteric coupling

…, KE Moeder, CA Sibbald, MI Zimmerman, KM Hart… - Biophysical …, 2019 - cell.com
Proteins are dynamic molecules that undergo conformational changes to a broad spectrum
of different excited states. Unfortunately, the small populations of these states make it difficult …

Evolutionary trend toward kinetic stability in the folding trajectory of RNases H

SA Lim, KM Hart, MJ Harms… - Proceedings of the …, 2016 - National Acad Sciences
Proper folding of proteins is critical to producing the biological machinery essential for cellular
function. The rates and energetics of a protein’s folding process, which is described by its …

[HTML][HTML] Home blood pressure monitoring

JM Weinfeld, KM Hart, JD Vargas - American family physician, 2021 - aafp.org
Home blood pressure monitoring provides important diagnostic information beyond in-office
blood pressure readings and offers similar results to ambulatory blood pressure monitoring. …

Tabtoxinine-β-lactam is a “stealth” β-lactam antibiotic that evades β-lactamase-mediated antibiotic resistance

KM Hart, M Reck, GR Bowman, TA Wencewicz - MedChemComm, 2016 - pubs.rsc.org
Tabtoxinine-β-lactam (TβL) is a phytotoxin produced by plant pathogenic strains of
Pseudomonas syringae. Unlike the majority of β-lactam antibiotics, TβL does not inhibit …
