Abstract
Despite many years of research into bacterial chemotaxis, the only well characterized system to date is that of E. coli. Even for E. coli, the direct ligand binding had been fully characterized only for aspartate and serene receptors Tar and Tsr. In 30 years since, no other direct receptor-ligand interaction had been described for bacteria, until the characterization of the C. jejuni aspartate and multiligand receptors (Hartley-Tassell et al. Mol Microbiol 75:710-730, 2010). While signal transduction components of many sensory pathways have now been characterized, ligand-receptor interactions remain elusive due to paucity of high-throughput screening methods. Here, we describe the use of microarray screening we developed to identify ligands, surface plasmon resonance, and saturation transfer difference nuclear magnetic resonance (STD-NMR) we used to verify the hits and to determine the affinity constants of the interactions, allowing for more targeted verification of ligands with traditional chemotaxis and in vivo assays described in Chapter 13 .

J Am Chem Soc. 2002 Aug 28;124(34):9984-5 Authors: Yan J, Kline AD, Mo H, Zartler ER, Shapiro MJ A novel method based on diffusion NMR for the epitope mapping of ligand binding is presented. The intermolecular NOE builds up during a long diffusion period and creates a deviation from the linearity. The ligand proton nearest the protein generates the strongest NOE from protein during the diffusion...
