  • PubMed Abstract: 
  • Neurotensin (NT) is a 13-residue neuropeptide that exerts multiple biological functions in the central and peripheral nervous system. Little is known about the structure of this neuropeptide, and what is known only concerns its C-terminal part. We determined here for the first time the structure of the full-length NT in membrane-mimicking environments by means of classical proton-proton distance constraints derived from solution-state NMR spectroscopy ...

    Neurotensin (NT) is a 13-residue neuropeptide that exerts multiple biological functions in the central and peripheral nervous system. Little is known about the structure of this neuropeptide, and what is known only concerns its C-terminal part. We determined here for the first time the structure of the full-length NT in membrane-mimicking environments by means of classical proton-proton distance constraints derived from solution-state NMR spectroscopy. NT was found to have a structure at both its N and C termini, whereas the central region of NT remains highly flexible. In TFE and HFIP solutions, the NT C-terminus presents an extended slightly incurved structure, whereas in DPC it has a beta turn. The N-terminal region of NT possesses great adaptability and accessibility to the microenvironment in the three media studied. Altogether, our work demonstrates a structure of NT fully compatible with its NTR-bound state.
