pH值和金属离子对尖吻蝮蛇抗凝血因子Ⅱ二级结构的影响（The Effects of pH and Metal Ions on the Secondary Structure of Anticogulation Factor Ⅱ Studed by CD Spectroscopy）
抗凝血因子Ⅱ 酸度(pH) 二级结构 圆二色谱
2010/8/25
圆二色谱(CD谱)测量表明，尖吻蝮蛇抗凝血因子Ⅱ(ACF Ⅱ)与抗凝血因子Ⅰ(ACF Ⅰ)的二级结构十分相似，它们的主要骨架构象都为反平行β-折叠和α-螺旋结构。pH值对天然ACF Ⅱ的构象有一定的影响，pH值从3到10增大时，α-螺旋含量逐渐减少，反平行β-折叠含量逐渐增大。钙和其他二价金属离子对ACF Ⅱ的骨架结构没有明显影响。三价稀土离子使ACF Ⅱ的α-螺旋含量升高，同时降低其β-转角和β...
