(2)H-(13)C HETCOR MAS NMR is performed on (2)H/(13)C/(15)N-Pro enriched A. aurantia dragline silk. Proline dynamics are extracted from (2)H NMR line shapes and T1 in a site-specific manner to elucidate the backbone and side chain molecular dynamics for the MaSp2 GPGXX β-turn regions for spider dragline silk in the dry and wet, supercontracted states.
（2）对氘/碳-13/氮-15 脯氨酸富集的金蛛拖牵丝进行氢-碳-13 异核多量子相干魔角旋转核磁共振实验。通过位点特异性方式从氢核磁共振线形和 T1 中提取脯氨酸动力学，以阐明处于干燥、湿润和超收缩状态的蜘蛛拖牵丝 MaSp2 GPGXXβ转角区域的主链和侧链分子动力学。
