Yeast killer toxin is a secreted protein that kills sensitive cells by forming an ion-conducting channel. The toxin is synthesized as a larger composite precursor containing two toxin subunits and an immunity protein. The processing and action of this precursor and its components provide an attractive system for studying these cellular events common to eukaryotes.
酵母杀伤毒素是一种分泌蛋白,通过形成离子传导通道杀死敏感细胞。该毒素以包含两个毒素亚基和一个免疫蛋白的更大复合前体形式合成。这种前体及其组分的加工和作用为研究真核生物共有的这些细胞事件提供了一个有吸引力的系统。
