中文摘要: 通过计算机模拟,预测大鳞副泥鳅生物活性以及其中血管紧张素转化酶(angiotensin converting enzyme,ACE)抑制肽的作用位点。通过UniProtKB数据库和蛋白质氨基酸序列比对选择大鳞副泥鳅蛋白,使用BIOPEP分析工具进行活性分析筛选出3种大鳞副泥鳅蛋白,使用Peptide、ExPASy和Predicted Antigenic Peptide等工具进行理化性质分析。将大鳞副泥鳅蛋白通过胃肠道模拟消化,分析释放的27种ACE抑制肽的一级结构、生物学潜力、理化性质和毒性特征。选择GPL和DGL进行分子对接。计算机预测方法确定出大鳞副泥鳅蛋白中具有28种生物活性,其中ACE抑制活性是主要活性之一。GPL与ACE活性位点S1、S2和S3成氢键相互作用,DGL与ACE活性位点S1和S2成氢键相互作用。
Abstract:Computer simulations were performed to predict the biological activity of loach(Paramisgurnus dabryanus)grandiflora and the site of action where angiotensin converting enzyme (ACE)inhibits the active peptide.The UniProtKB database was scrutinized and protein amino acid sequence comparisons were performed to select loach protein.The BIOPEP analysis tool was used to perform activity analysis to screen out three types of loach protein.Peptide,ExPASy and Predicted Antigenic Peptide analyses of the physical and chemical properties of loach protein digested through the gastrointestinal tract determined the primary structure,biological potential,physicochemical properties,and toxicity characteristics of the 27 ACE inhibitor peptides released.GPL and DGL were selected for molecular docking analyses.Computer predictions identified 28 biological activities of the loach protein.ACE inhibitory activity was one of the main activities.GPL interaction with ACE active sites S1,S2,and S3,and DGL interaction with ACE active sites S1and S2occurred via hydrogen bonding.
