The Escherichia coli serine receptor senses serine levels in the environment and transmits this information across the bacterial inner membrane to modulate a protein phosphorylation cascade which controls swimming behavior. Solid-state nuclear magnetic resonance (NMR) has been used to characterize specific structural features of the ligand binding site interactions in the intact, membrane-bound Ser receptor. Rotational-echo double-resonance (REDOR) experiments on [15N]Ser bound to a [1-13C]Phe-receptor preparation are used to measure distances between the ligand amino group and the carbonyls of two phenylalanine residues in the ligand binding pocket. The results indicate two 4.0 +/- 0.2 A distances, in excellent agreement with the X-ray crystal structure of a soluble fragment of the homologous aspartate receptor [Milburn et al. (1991) Science 254, 1342-1347]. These results confirm the similarity of the binding sites of the Asp and Ser receptors, and demonstrate the feasibility of using solid-state NMR measurements to obtain specific structural information on the 120 kDa intact receptor for probing transmembrane signaling mechanisms.

Abstract Formation of the complex between human immunodeficiency virus type-1 Tat protein and the transactivation response region (TAR) RNA is vital for transcriptional elongation, yet the structure of the Tat-TAR complex remains to be established. The NMR structures of free TAR, and TAR bound to Tat-derived peptides have been obtained by solution NMR, but only a small number of intermolecular NOEs could be identified unambiguously, preventing the determination of a complete structure. Here we show that a...
