Solution Structure and NMR Chemical Shift Perturbations of the Arabidopsis BCCP1 Identify Intersubunit Interactions Potentially Involved in the Assembly of the Heteromeric Acetyl-CoA Carboxylase
Biotin carboxyl carrier protein (BCCP) is a subunit of the heteromeric acetyl-CoA carboxylase (htACCase), and it chemically links the two half-reactions that constitute the formation of malonyl-CoA from acetyl-CoA, a critical reaction in fatty acid biosynthesis. Because plants are a major source of edible fats and oils, it is important to understand the structural organization of the plant htACCase, relative to its potential to regulate fatty acid biosynthesis in plant plastids. Moreover, unique...
[NMR paper] Improved analysis of NMR chemical shift perturbations through an error estimation method
Improved analysis of NMR chemical shift perturbations through an error estimation method
In solution NMR, chemical shift perturbation (CSP) experiments are widely employed to study intermolecular interactions. However, excluding the nonsignificant peak shift is difficult because little is known about errors in CSP. Here, to address this issue, we introduce a method for estimating errors in CSP based on the noise level. First, we developed a technique that involves line shape fitting to estimate errors in peak position via Monte Carlo simulations. Second, this technique was applied...

[NMR paper] pH Effects Can Dominate Chemical Shift Perturbations in 1H,15N-HSQC NMR Spectroscopy for Studies of Small Molecule/?-Synuclein Interactions
pH Effects Can Dominate Chemical Shift Perturbations in 1H,15N-HSQC NMR Spectroscopy for Studies of Small Molecule/?-Synuclein Interactions
¹H,^(15)N-Heteronuclear Single Quantum Coherence (HSQC) NMR is a powerful technique that has been employed to characterize small-molecule interactions with intrinsically disordered monomeric ?-Synuclein (aSyn). We report how solution pH can impact the interpretation of aSyn HSQC NMR spectra and demonstrate that small-molecule formulations (e.g., complexation with acidic salts) can lower sample pH and confound interpretation of drug binding and...

Proteinâ??ligand structure guided by backbone and side-chain proton chemical shift perturbations
Proteinâ??ligand structure guided by backbone and side-chain proton chemical shift perturbations
Abstract
The fragment-based drug design approach consists of screening libraries of fragment-like ligands, to identify hits that typically bind the protein target with weak affinity ( \(100\,\upmu \hbox {M}\) â??5Â*mM). The determination of the proteinâ??fragment complex 3D structure constitutes a crucial step for uncovering the key interactions responsible for...
