Data for the article entitled "Dual mode of voltammetric studies on Cu(II) complexes of His2 peptides: phosphate and peptide sequence recognition"

Files include the data presented in the manuscript entitled "Dual mode of voltammetric studies on Cu(II) complexes of His2 peptides: phosphate and peptide sequence recognition" by A. Tobolska et al. (https://doi.org/10.1039/D2DT03078K).In this work, we designed a library of nine His2 peptides consisting of Aβ5-9 and eight analogs whose binary Cu(II) complexes represent potential phosphate-binding receptors. We performed UV-vis spectroscopic studies on the formation of Cu(II)-His2 peptide complexes. Then, we employed Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV) to check the electrochemical properties of binary Cu(II) complexes of His2 peptides as well as to compare the response of the complexes toward the selected anions. Using the same data set, we discriminated the His2 peptide sequences by Principal Component Analysis (PCA). Data (.csv, .txt) includes:1) Voltammetric curves of binary Cu(II)-His2 peptide complexes (CV, DPV)2) Voltammetric curves of ternary Cu(II)-His2 peptide/phosphate systems (DPV)3) UV-vis spectra registered during the pH titrations of Cu(II)-His2 peptide complexes

本数据集包含A. Tobolska等人发表于题为"His2肽的铜(II)配合物伏安法双模式研究：磷酸根与肽序列识别"（DOI: 10.1039/D2DT03078K）的手稿中的相关数据。本研究构建了含9条His2肽的肽库，其中1条为淀粉样蛋白β5-9（Aβ5-9），另有8条类似物；这些肽的二元铜(II)配合物可作为潜在的磷酸根结合受体。我们通过紫外-可见光谱法研究了Cu(II)-His2肽配合物的形成过程；随后采用循环伏安法（Cyclic Voltammetry, CV）与差分脉冲伏安法（Differential Pulse Voltammetry, DPV），表征了His2肽二元铜(II)配合物的电化学性质，并对比了该类配合物对选定阴离子的响应情况。此外，本研究基于同一数据集，通过主成分分析（Principal Component Analysis, PCA）对His2肽序列进行了区分。本数据集的.csv与.txt格式文件包含以下内容：1）二元Cu(II)-His2肽配合物的伏安曲线（CV、DPV）；2）三元Cu(II)-His2肽/磷酸根体系的伏安曲线（DPV）；3）Cu(II)-His2肽配合物pH滴定过程中记录的紫外-可见光谱。
