摘要: 用分子模拟软件研究肝素与HIV-1膜表面蛋白gp120的相互作用.将肝素中的单糖、二糖和三糖片段作为探针对gp120蛋白进行搜索,统计分析确定肝素结合区域.用肝素六糖片段和结合区域进行反应分子对接,获得两种结合模式.最终建立的模型能够很好地解释肝素体外抑制HIV-1的现象,同时对其机理进行了推测.

关键词: gp120, 肝素结合区域, 探针, 分子对接

Abstract: Molecular simulation software are used to investigate the interaction between HIV-1 envelope protein gp 120 and heparin. Monosaccharide, disaccharide and trisaccharide of heparin are used as the probe molecules to make a global search around protein gp 120. After statistics analysis, we found the most favorable binding domain on gp 120 to heparin, and got two binding model which could be used to interpret the phenomenon that heparin could inhibit HIV-1 in vitro very well by docking heparin hexasaccharide to the binding domain.

Key words: gp 120, Heparin binding domain, Probe, Docking
