Abstract

Ion mobility-mass spectrometry (IM-MS) unraveled different conformational stability in Zn-metallothionein-2. We introduced a new molecular dynamics simulation approach that permitted the exploration of all of the conformational space confirming the experimental data, and revealed that not only the Zn-S bonds but also the α-β domain interactions modulate protein unfolding.

摘要

离子淌度-质谱联用（IM-MS）揭示了锌金属硫蛋白-2 中的不同构象稳定性。我们引入了一种新的分子动力学模拟方法，该方法允许探索所有构象空间，证实了实验数据，并表明不仅 Zn-S 键，而且 α-β 结构域相互作用也调节蛋白质的展开。
