项目摘要
Canine milk lysozyme (CML) is a calcium binding protein belonging to the lysozyme family. Although CML and goat α-lactalbumin (GLA) are highly homologous, it was found in recent experimental results that the unfolding pathway of CML is different from that of GLA. We examined the difference between the unfolding pathways of CML and GLA by performing all-atom molecular dynamics simulations. As a result, we found that the difference of the unfolding pathways is due to the presence of absence of local interactions in these proteins. In addition, we developed a novel method for the structure transitions based on third-order nonlinear spectroscopy.
犬乳溶菌酶(CML)是一种钙结合蛋白,属于溶菌酶家族。虽然CML与山羊α-乳清蛋白(GLA)具有高度同源性,但最近的实验结果发现CML的展开途径与GLA不同。我们通过进行全原子分子动力学模拟来检查CML和GLA展开途径之间的差异。结果,我们发现展开途径的差异是由于这些蛋白质中缺乏局部相互作用的存在。此外,我们还开发了一种基于三阶非线性光谱的结构跃迁新方法。
