Gly-Ile-Gly-Ala-Val-Leu-Lys-Val-Leu-Thr-Thr-Gly-Leu-Pro-Ala-Leu-Ile-Ser-Trp-Ile-Lys-Arg-Lys-Arg-Gln-Gln-NH2

一般說明

化学结构:肽
蜂毒肽本质上是疏水性的,除了靠近 C 末端的 Lys-Arg-Lys-Arg 序列区域。这种结构特征使蜂毒肽成为一种高度表面活性和强大的直接溶血剂。†该编码蛋白包含 26 个氨基酸。蜂毒肽单体形式的分子量为 2,840 Da,四聚体形式的分子量约为 12,500 Da。

應用

蜜蜂毒液中的蜂毒肽已被用于:
  • 在3-(4, 5-二甲基噻唑-2-基)-2,5二苯基溴化四唑(MTT)测定中确定其对人细胞系生长的细胞毒性作用。
  • 体外研究蜂毒肽对伯氏疏螺旋体生长的抗菌活性。
  • 作为溶血试验中的阳性对照和作为抗 HeLa 细胞的细胞毒剂。

生化/生理作用

以 Ca 2 + 依赖性方式结合钙调素;抑制 Na + -K + -atp 酶。
蜂毒肽通过延长体外凝血时间作为抗凝蛋白。蜂毒肽抑制 S100 钙结合蛋白 B(S100B)的活性,在癫痫治疗中发挥重要作用。
