In this paper, we present experimental evidence for the identity of the ste6 gene product as a UDP-glucose dehydrogenase.

以pET-30a为载体，克隆并在大肠杆菌BL21(DE3)中进行了ste6基因的表达，对该基因的克隆、表达与性质进行了研究。

Inactivation of plant virus and the indictor of animal virus by disinfect agent, mechanism of removing and inactivation of viruses by hydroxide modified sand pillar.4. 1. The results of the different microorganism resistances to the disinfect agent of chlorine shown that the indictor of E. coli usually used to evaluation the water body polluted by human deject is no useable.

4.1。不同微生物对自游氯消毒的抗性显示，大肠杆菌作为病毒污染指示物及水体环境病原微生物危险性评估的指标已失去真正的意义，而B.fp则是一个更为合理与科学的水体病毒污染与去除的指示物。

The most common causative strain of gallstone pancreatitis is Bacterium coli. The drug-resistant strain emerges maybe due to bacterium immigration and delitescence in gallbladder mucosa.

胆源性胰腺炎感染细菌主要以大肠杆菌为主，耐药菌株的出现可能与细菌向胆囊黏膜迁移并发生变异，以L型细菌的形式潜伏于胆囊有关。

The rPEDF was purified by Ni-NTA on denature condition. The concentration of the rPEDF was determined by Bradford method.

采用PCR法扩增人PEDFcDNA，将其克隆到pET32a载体中，在大肠杆菌BL21中表达人PEDF蛋白。

Results:Baihuling pyretolysis powder is most sensitive to Diplococcus lanceolatus and Staphylococcus aureus,sentive to beta streptococcus ,insensitivity to Bacillus coli.

结果：白虎羚退热散对肺炎双球菌及金黄色葡萄球菌最敏感，对乙型链球菌敏感，对大肠杆菌不敏感。

Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

从胺基酸序列分析显示，竹嵌纹病毒复制酵素中间区域的类解螺旋酵素具有解螺旋酵素的保留性胺基酸区域，经实验显示此蛋白具有ATPase和RNA 5'-triphosphatase活性，而且是依赖镁离子进行反应的，其中保留性胺基酸的突变会破坏其催化能力，说明这在大肠杆菌表达的蛋白质经过变性及重新摺叠的过程，具有和其他SF 1解螺旋酵素相似的特性。
