title: Solid-state NMR evidence for elastin-like beta-turn structure in spider dragline silk.
abstract: Two-dimensional homo- and heteronuclear solid-state MAS NMR experiments on (13)C/(15)N-proline labeled Argiope aurantia dragline silk provide evidence for an elastin-like beta-turn structure for the repetitive Gly-Pro-Gly-X-X motif prevalent in major ampullate spidroin 2 (MaSp2).
