…, WB Arendall, JJ Headd, DA Keedy… - … Section D: Biological …, 2010 - scripts.iucr.org
MolProbity is a structure-validation web service that provides broad-spectrum solidly based
evaluation of model quality at both the global and local levels for both proteins and nucleic …

MolProbity: More and better reference data for improved all‐atom structure validation

…, LL Videau, LN Deis, V Verma, DA Keedy… - Protein …, 2018 - Wiley Online Library
This paper describes the current update on macromolecular model validation services that
are provided at the MolProbity website, emphasizing changes and additions since the …

Alternate states of proteins revealed by detailed energy landscape mapping

MD Tyka, DA Keedy, I André, F DiMaio, Y Song… - Journal of molecular …, 2011 - Elsevier
What conformations do protein molecules populate in solution? Crystallography provides a
high-resolution description of protein structure in the crystal environment, while NMR …

CryptoSite: expanding the druggable proteome by characterization and prediction of cryptic binding sites

…, TJ Rettenmaier, L Bichmann, DA Keedy… - Journal of molecular …, 2016 - Elsevier
Many proteins have small-molecule binding pockets that are not easily detectable in the
ligand-free structures. These cryptic sites require a conformational change to become apparent; …

Mapping the conformational landscape of a dynamic enzyme by multitemperature and XFEL crystallography

DA Keedy, LR Kenner, M Warkentin, RA Woldeyes… - Elife, 2015 - elifesciences.org
10.7554/eLife.07574.001 Determining the interconverting conformations of dynamic proteins

[PDF][PDF] Crystal cryocooling distorts conformational heterogeneity in a model Michaelis complex of DHFR

DA Keedy, H Van Den Bedem, DA Sivak, GA Petsko… - Structure, 2014 - cell.com
Most macromolecular X-ray structures are determined from cryocooled crystals, but it is
unclear whether cryocooling distorts functionally relevant flexibility. Here we compare …

An expanded allosteric network in PTP1B by multitemperature crystallography, fragment screening, and covalent tethering

DA Keedy, ZB Hill, JT Biel, E Kang, TJ Rettenmaier… - Elife, 2018 - elifesciences.org
10.7554/eLife.36307.001 Allostery is an inherent feature of proteins, but it remains challenging
to reveal the mechanisms by which allosteric signals propagate. A clearer understanding …

OSPREY: protein design with ensembles, flexibility, and provable algorithms

…, KE Roberts, I Georgiev, RH Lilien, DA Keedy… - Methods in …, 2013 - Elsevier
We have developed a suite of protein redesign algorithms that improves realistic in silico
modeling of proteins. These algorithms are based on three characteristics that make them …

Room-temperature crystallography reveals altered binding of small-molecule fragments to PTP1B

…, R Talon, D Axford, H Orins, F von Delft, DA Keedy - Elife, 2023 - elifesciences.org
Much of our current understanding of how small-molecule ligands interact with proteins stems
from X-ray crystal structures determined at cryogenic (cryo) temperature. For proteins alone…
