Ligand Screening of Membrane Proteins Embedded in Nanodiscs: How to Manage Non-Specific Interactions in Weak Affinity Chromatography?

Molecules
Miniaturized weak affinity chromatography is emerging as an interesting alternative to conventional biophysical tools for performing fragment-screening studies in the context of fragment-based drug discovery.

Affinity chromatography of native and recombinant proteins-from receptors for insulin and IGF-I to recombinant single chain antibodies

Frontiers in Endocrinology, 2015
Affinity chromatography is an efficient method to isolate proteins by taking advantage of their affinities for specific molecules such as substrates, inhibitors, antigens, ligands, antibodies, and other interacting molecules including subunits. Nowadays,

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Incremental Modification in the Existing Approaches for Affinity Chromatographic Enrichment of Phosphoproteins Improves Their Profile in Liquid Chromatography‐Tandem Mass Spectrometry Analysis

Analytical Science Advances
Cell signalling is a vital process in cell physiology, which is driven by protein phosphorylation. Global phosphoproteome analysis by liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) has thus gained importance in cell signalling research ...

Consecutive Affinity and Ion-Exchange Chromatography for AAV9 Vectors Purification

Biomedicines
Background: Irrespective of the rapid development of AAV-based gene therapy, the production of clinical-grade vectors has a bottleneck resulting from product-related impurities such as empty and partially filled capsids, which lack a functional ...

Single bead affinity detection (SINBAD) for the analysis of protein-protein interactions. [PDF]

PLoS ONE, 2008
We present a miniaturized pull-down method for the detection of protein-protein interactions using standard affinity chromatography reagents. Binding events between different proteins, which are color-coded with quantum dots (QDs), are visualized on ...

Extending the Affinity Range of Weak Affinity Chromatography for the Identification of Weak Ligands Targeting Membrane Proteins

Molecules, 2023
The identification of weak-affinity ligands targeting membrane proteins is of great interest in Fragment-Based Drug Design (FBDD). Recently, miniaturized weak affinity chromatography (WAC) has been proposed as a valuable tool to study interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Subfractionation of human high density lipoproteins by heparin-Sepharose affinity chromatography.

Journal of Lipid Research, 1980
A reproducible and quantitative subfractionation of human high density lipoproteins (HDL) by heparin-Sepharose affinity chromatography has been developed. Two elution methods (A and B) were used to subfractionate HDL(2) (d 1.063-1.125 g/ml) or total HDL (
