Angiotensin 1-7
Overview
We report the complete sequence-specific hydrogen NMR assignments of, vasoactive peptide angiotensin-(1-7) (Ang-(1-7)). Assignments of the, majority of the resonances were accomplished by COSY, TOCSY, and ROESY, peak coordinates at 400MHz and 600MHz. Long-side-chain amino acid spin, system identification was facilitated by long-range coherence transfer, experiments (TOCSY). Problems with overlapped resonance signals were, solved by analysis of heteronuclear 2D experiments (HSQC and HMBC)., Nuclear Overhauser effects (NOE) results were used to probe peptide, conformation. We show that the inclusion of the angiotensin-(1-7) tyrosine, residue is favored in inclusion complexes with beta-cyclodextrin. QM/MM, simulations at the DFTB/UFF level confirm the experimental NMR findings, and provide detailed structural information on these compounds in aqueous, solution.
