A method that allows to estimate the influence of single amino acid substitutions on the stability of proteins with known three-dimensional structure was developed. The role of 20 different physico-chemical properties of amino acids and some characteristics of the three-dimensional structure in the destabilization of protein structure caused by mutations was analyzed. Analysis of 54 proteins led us to reveal the characteristics of the three-dimensional structure. The parameters of the method were calculated on the basis of experimental data for 330 mutant human hemoglobins. The prediction accuracy of the method is on average 81%. The method may be used for the analysis of the total mutational spectra of the proteins and also for the estimation of effects of the single amino acid substitution on the protein structure in gene-engineering experiments.
开发了一种能够估算单个氨基酸取代对已知三维结构蛋白质稳定性影响的方法。分析了氨基酸的20种不同物理化学性质以及三维结构的一些特征在突变导致蛋白质结构不稳定中的作用。对54种蛋白质的分析使我们揭示了三维结构的特征。该方法的参数是根据330种突变型人血红蛋白的实验数据计算得出的。该方法的预测准确率平均为81%。该方法可用于分析蛋白质的总突变谱,也可用于基因工程实验中估算单个氨基酸取代对蛋白质结构的影响。
