Abstract

Fourier transform infrared and laser Raman spectroscopies were used to study the effects of dodecylpyridinium bromide on the conformation of haemoglobin, myoglobin, bovine serum albumin, ribonuclease, ovalbumin, lysozyme, trypsin and beta-lactoglobulin in aqueous solution. Addition of the cationic detergent caused a decrease in alpha-helix conformation in highly helical proteins. At low detergent concentrations stabilization of beta-sheet conformation was observed.

摘要

采用傅里叶变换红外光谱和激光拉曼光谱研究了十二烷基溴化吡啶对水溶液中血红蛋白、肌红蛋白、牛血清白蛋白、核糖核酸酶、卵清蛋白、溶菌酶、胰蛋白酶和β-乳球蛋白构象的影响。添加阳离子去污剂会导致高度螺旋化蛋白质的α-螺旋构象减少。在低去污剂浓度下，观察到β-折叠构象的稳定。
