Domain Interactions Determine the Conformational Ensemble of the Periplasmic Chaperone SurA

October 1, 2020
Author(s)
Dagan C. Marx, Mathis J. Leblanc, Ashlee M. Plummer, Susan T. Krueger, Karen G. Fleming
SurA is thought to be the most important periplasmic chaperone for outer membrane protein biogenesis. Its structure is composed of a core region and two peptidylprolyl isomerase domains, termed P1 and P2, connected by flexible linkers. As such these three

Characterization of an Extensive Interface on Vitronectin for Binding to Plasminogen Activator Inhibitor-1: Adoption of Structure in an Intrinsically Disordered Region

December 24, 2019
Author(s)
Letitia O. Puster, Christopher B. Stanley, Vladmir N. Uversky, Joseph E. Curtis, Susan T. Krueger, Yuzhuo Chu, Cynthia B. Peterson
Small-angle neutron scattering (SANS) measurements were used to characterize vitronectin, a protein found in human plasma and tissues that functions in regulating cell adhesion and migration, as well as proteolytic cascades that affect blood coagulation

ROTDIF-web and ALTENS: GenApp-based Science Gateways for Biomolecular Nuclear Magnetic Resonance (NMR) Data Analysis and Structure Modeling

September 23, 2019
Author(s)
Yuexi Chen, Cheol Jeong, Alexey Savelyev, Susan T. Krueger, Joseph E. Curtis, Emre H. Brookes, David Fushman
Proteins and nucleic acids participate in essentially every biochemical process in living organisms, and the elucidation of their structure and motions is essential for our understanding how these molecular machines perform their function. Nuclear Magnetic

Understanding the Static Interfacial Polymer Layer by Exploring the Dispersion States of Nanocomposites

May 5, 2019
Author(s)
Anne-Caroline Genix, Vera Bocharova, Bobby Carroll, Michelle Lehmann, Tomonori Saito, Susan T. Krueger, Lilin He, Philippe Dieudonne-George, Alexei P. Sokolov, Julian Oberdisse
The dynamic and static properties of the interfacial region between polymer and nanoparticles have wide-ranging consequences on performances of nanomaterials. The thickness and density of the static layer are particularly difficult to assess experimentally

Sokolov, Robert Sutherland, Norman Wagner, Michael NMN Weinrich, Kevin Weiss, Troy Wymore, Yang Zhang, Jeremy C. Smith
The scattering of neutrons can be used to provide information on the structure and dynamics of biological systems on multiple scales of length and time. Pursuant to an NSF-funded workshop in February 2018, we review recent developments in this field as

Structural Basis for the Inhibitory Effects of Ubistatins in the Ubiquitin-Proteasome Pathway

December 5, 2017
Author(s)
Mark A. Nakasone, Timothy A. Lewis, Olivier Walker, Anita Thakur, Wissam Mansour, Carlos A. Castaneda, Jennifer L. Goeckeler-Fried, Frank Parlati, Tsui-Fen Chou, Ortal Hayat, Daoning Zhang, Christina M. Camara, Steven M. Bonn, Urszula K. Nowicka, Susan T. Krueger, Michael H. Glickman, Jeffrey L. Brodsky, Raymond J. Deshaies, David Fushman
The success of proteasome inhibitors has led to intense efforts to discover points of therapeutic intervention for nearly every component of the ubiquitin-proteasome system. The discovery of ubistatins, small molecules that inhibit proteasomal degradation

December 1, 2016
Author(s)
Priyanka Bhattacharya, Uma Shantini Ramasamy, Susan T. Krueger, Joshua W. Robinson, Barbara J. Tarasevich, Ashlie Martini, Lelia Cosimbescu
In an effort to look for correlations between viscosity index trends of polymers in oils and size changes of polymers in solution with temperature, the determination of the size of thermo-responsive polymers of various architectures (linear, comb, star

Role of Molecular Flexibility and Colloidal Descriptions of Proteins in Crowded Environments from Small-Angle Scattering
