Detection of Metabolite-Protein Interactions in Complex Biological Samples by High-Resolution Relaxometry: Towards Interactomics by NMR

In this manuscript, we introduce an NMR method to investigate the interaction of metabolites and other small molecules with proteins in biological fluids. Our approach, based on high-resolution relaxometry identifies the interaction of small molecules with proteins in blood serum and is used for the quantitative analysis of binding competition in situ.
