This data article contains complementary results related to the paper "Effect of metal ions on the binding reaction of (-)-epigallocatechin gallate to -lactoglobulin" (Zhang et al., 2017) [1]. Data was obtained by circular dichroism (CD) spectroscopy to investigate potential -lactoglobulin (-Lg) conformational changes with different concentrations of EGCg and Cu or Al added to -Lg. 500 µL of the 25 µM -Lg solution containing EGCg (25 µM) or metal ions (0-500 µM) were measured, and the spectra were recorded. CD spectroscopy data present in this article indicated that the -Lg-Cu, -Lg-Al and -Lg-EGCg interaction resulted in unfolding of the secondary structure of -Lg.
本数据文章包含与论文《金属离子对（-）-表没食子儿茶素没食子酸酯与β-乳球蛋白结合反应的影响》（Zhang等人，2017年）[1]相关的补充结果。通过圆二色光谱（CD）获得数据，以研究在向β-乳球蛋白（β-Lg）中添加不同浓度的表没食子儿茶素没食子酸酯（EGCg）和铜或铝时，β-乳球蛋白（β-Lg）潜在的构象变化。测量了500微升含有EGCg（25微摩尔）或金属离子（0 - 500微摩尔）的25微摩尔β-Lg溶液，并记录光谱。本文中呈现的CD光谱数据表明，β-Lg-铜、β-Lg-铝和β-Lg-EGCg相互作用导致β-Lg二级结构展开。
