WebChemical Shift Perturbation Analysis Tutorial. Find out how to create a Spectrum Group for a series of spectra, copy your peak assignments between spectra, view … Chemical shift perturbation (CSP, also known as chemical shift mapping and complexation-induced changes in shift, CIS) is a common technique for demonstrating ligand binding to proteins, locating the binding site, and measuring ligand affinity. The most common application is to … See more Where there are two or more equivalent binding sites, then Eq. 4can be modified to where n is the number of equivalent sites [14]. If there are two different binding sites, then the analysis … See more This is a common problem, though one not often discussed. It is frequently observed that addition of ligand causes cloudiness in the solution, and loss of intensity in the NMR spectrum, implying precipitation of a complex or possibly … See more It is rare that a protein binds to its ligand without also undergoing conformational change, especially when the protein is an enzyme or is modulated allosterically. Under these … See more The discussion so far is only valid for fast exchange, when koff≫ Δν (the difference in chemical shift between free and bound signals, measured in Hz). There are several important consequences of slower exchange. 1. 1. In … See more

WebJan 4, 2024 · We also investigated the substrate specificity of CaACP using chemical shift perturbation (CSP). Our study confirmed that CaACP has a substrate specificity for BCFAs and offered essential insights into the development of antibiotics against C. acnes at the molecular level. Results. Comparison with other ACP sequences. WebApr 1, 2024 · Bile acids have been reported as important cofactors promoting human and murine norovirus (NoV) infections in cell culture. The underlying mechanisms are not resolved. Through the use of chemical shift perturbation (CSP) NMR experiments, we identified a low-affinity bile acid binding site of a human GII.4 NoV strain.
