pertussis toxin meaning in Chinese

百日咳毒素

It was found that plc activity was stimulated by both exogenous purified calmodulin and heterotrimeric g protein agonist cholera toxin . while , the stimulated effect on plc activity caused by exogenous calmodulin was inhibited by heterotrimeric g protein antagonist pertussis toxin , and plc antagonist u - 73122 inhibited the effect caused by cholera toxin . we also measure the free ca ~ ( 2 + ) level in germinating pollen grains , and found that exogenous purified calmodulin was able to increase the free ca ~ ( 2 + ) level , and their effects on ca ~ ( 2 + ) level were inhibited by u - 73122
实验中，利用[ ~ 3h ] pip _ 2和花粉原生质体共同孵育的体系，检测出了百合花粉细胞具有依赖pip _ 2的plc活性；利用该体系还检测出外源钙调素可促进plc的活性，其中10 ~ ( - 9 ) m的钙调素可使plc的活性提高三倍；异三聚体g蛋白的激活剂ctx可以激活plc的活性，而其抑制剂ptx可明显抑制plc活性；外源钙调素的这种作用可以被ptx抑制；而plc抑制剂u - 73122抑制ctx对plc的激活效应。
