当反应性巯基 SH1 已被封闭的肌球蛋白亚片段 1 衍生物与 N,N'-对亚苯基二酰亚胺或 5,5'-二硫代双(2-硝基苯甲酸)反应时,20-kDa 结构域的反应性巯基 SH2 与重链 50-kDa 结构域的硫醇交联。交联导致大量 Mg2+-核苷酸稳定捕获在 ATP 酶位点上。
When myosin subfragment 1 derivatives in which the reactive sulfhydryl SH1 has been blocked react with N,N'-p-phenylenedimaleimide or 5,5'-dithiobis(2-nitrobenzoic acid), the reactive sulfhydryl group SH2 of the 20-kDa domain is crosslinked with a thiol of the 50-kDa domain of the heavy chain. The crosslink induces the stable trapping of a significant amount of Mg2+-nucleotide in the ATPase site.
