Methionine sulfoxide was detected in the resilium (internal hinge ligament) of a surf clam by high-resolution solid-state 13C-NMR spectroscopy involving cross-polarization and magic angle spinning, using no chemical procedure. The results support the previous report [Kikuchi, Y. and Tamiya, N. (1981) J. Biochem. (Tokyo) 89, 1975-1976] on a high content of methionine sulfoxide observed by chemical methods in the resilium protein of surf clam species.
通过采用交叉极化和魔角旋转的高分辨率固态13C核磁共振光谱法，在不进行任何化学处理的情况下，在一种 surf clam 的 resilium（内部铰合韧带）中检测到了甲硫氨酸亚砜。这些结果支持了之前的报告[菊池洋和玉屋直（1981年），《生物化学杂志》（东京）89卷，1975 - 1976页]，该报告通过化学方法观察到 surf clam 物种的 resilium 蛋白中甲硫氨酸亚砜含量很高。
