摘要 蓝藻抗病毒蛋白N(Cyanovirin-N)简称CV-N,相对分子质量11kD,含有101个氨基酸残基,主要是由β-叠片结构形成的链状蛋白,其中有2个内部二硫键。通过基因重组表达纯化的产物,其结构和活性均与天然CV-N相同。CV-N与人类免疫缺陷病毒(HIV)包膜糖蛋白120(gp120)具有高度亲和性,并能够阻断由包膜蛋白介导的细胞融合过程从而阻止病毒的扩散。CV-N不仅能够有效地抑制多个亚型的人类免疫缺陷病毒1(HIV-1),2(HIV-2),猴免疫缺陷病毒(SIV),而且对单纯疱疹病毒、流行性感冒病毒及其他一些包膜病毒也有抑制作用。CV-N的若干特性使其有可能成为一种非常有价值的新型抗病毒药物。
