用电子自旋共振光谱法研究了金属硫蛋白、铁离子和一氧化氮的相互作用。兔肝apoMT 2或Zn-MT 2与Fe2+和NO混合后，可得到g值分别为2.013和2.039的顺磁性产物。这些都是具有化学计量学的亚硝基硫代铁Fe(NO)2(SR)2的特征。用牛心线粒体乌头酸酶作为铁源时，不产生本品。
The interaction of metallothionein, Fe2+, and nitric oxide has been examined by electron spin resonance spectroscopy. When either apoMT 2 or Zn-MT 2 from rabbit liver was mixed with Fe2+and NO, paramagnetic products with g values of 2.013 and 2.039 were found. These are characteristic of iron nitrosyl thiolates with stoichiometry, Fe(NO)2(SR)2. This product was not generated when beef heart mitochondrial aconitase was used as the source of iron.
