项目摘要
Carbohydrate-recognition mechanisms of calcium-dependent lectins, which play important roles in molecular recognition systems in organisms, were analyzed, and a novel artificial lectin with a designed binding-specificity was produced. In addition, site-directed mutational and three-dimensional structural analyses of the hemolytic lectin CEL-III revealed that it forms heptamers in target cell membrane with extensive conformational changes, forming the transmembrane pores that lead to hemolysis or cell death. These results may provide valuable information on various pore-forming toxin proteins widely distributed in the nature.
分析了钙依赖性凝集素的碳水化合物识别机制,它们在生物体中在分子识别系统中起重要作用,并产生了具有设计结合特异性的新型人工凝集素。此外,溶血性凝集素CEL-III的位置定向的突变和三维结构分析表明,它在靶细胞膜中形成了具有广泛构象变化的靶细胞膜中的七聚体,形成了导致溶血或细胞死亡的跨膜孔。这些结果可能会提供有关大自然中广泛分布的各种孔形成毒素蛋白的有价值信息。
