pH值和钙离子对尖吻蝮蛇抗血小板凝集素二级结构的影响（Effects of pH Value and Ca2+ Ion on the Secondary Structure of Agkisacutacin from Agkistrodon Acutus Venom）
抗血小板凝集素 二级结构 圆二色谱 拉曼光谱 红外光谱
2010/8/25
尖吻蝮蛇毒中抗血小板凝集素是凝血因子IX/凝血因子X结合蛋白，它具有抗凝血和抑制血小板凝集双重活性。用红外光谱、拉曼光谱和CD谱研究了抗血小板凝集素的二级结构以及pH值和钙离子对其二级结构的影响。用CD谱测得，在水溶液中，抗血小板凝集素的主要骨架构象为β-折叠(26.3%)和α-螺旋(19.6%)结构。拉曼光谱显示，在粉末状态，其α-螺旋含量显著降低。CD谱还表明，抗血小板凝集素在pH值3.0～1...
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...
