可抑制的

This protein reduced antibody titer in mice immunized with BSA. Following the deletion of sCD152, however, there was no obvious inhibitory effect on the primary immune response triggered by the nonrelevant antigen OVA, indicating that sCD152 had an antigen-specific immunosuppressive effect. We designed a new vector, pPIC-HE-sCD152, to get entirely native sCD152 without His-tag.

为了获得既带有纯化配体表位又带有可剪切序列的可溶性sCD152蛋白，我们设计构建了含有His-tag和肠激酶识别切割序列DDDDK的sCD152表达载体pPIC-HE-sCD152，结果这一表达载体在毕赤氏酵母中同样高效分泌表达出目的蛋白，大量纯化后用肠激酶酶切去除His-tag，用以进一步功能实验，初步结果表明具有体外细胞免疫抑制功能。

The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。
