二聚体

Based on the biochemical analysis of the two proteins in vitro, the results of yeast two-hybrid experiment and protein-interaction in both wild type cells and C48 strain, we conclude HetR can form a homodimer through the Cys48 residue. We also show that the dimerization is required for heterocyst differentiation.

基于体外两种蛋白的性质比较和酵母双杂交的结果，并结合相应蓝细菌野生型和突变株C48A中HetR蛋白性质的体内研究表明：HetR蛋白可以通过第48位半胱氨酸残基形成共价结合的同源二聚体，该同源二聚体是异型胞正常分化所必需的。

In addition, our data indicated that the conformation of NR1 subunit homodimers was affected by the partner NR2 subunits during the formation of heteromeric receptor complexes, which might underlie the mechanism by which NR2 subunits modify NMDA receptor function. We also found that in the endoplasmic reticulum, even the whole extracellular N-terminal domain was truncated, the NR subunit could form homomers or heteromers with each other in HEK293 cells, which indicate that the NT is not the crucial element for the receptor assembly.

同时，通过推算FRmax，我们发现NR亚单位同二聚体的N端构象在形成功能性受体的前后是发生变化的，特别是对于NR1a亚单位，其同二聚体的N端构象会因与其配对的NR2亚单位的不同而发生不同的改变。

Erve growth factor combined with its receptor, activated Ras - MAP kinase , mitogen - activated protein kinase kinase is the important regulating factor that make IkB kinase, IKK, phosphated, IkB kinase make the IκBα:(the subunit of NF -κB ) phosphated, the phosphated IkBα degraded, and p65 - p50 heterodimer can be formed, then the heterodimer translocated to nucleus and combined with the promoter domain or other consensus sequence.

GF与其受体相结合，最后可以激活Ras-有丝分裂激活的蛋白激酶途径，有丝分裂激活的蛋白酶激酶(MEKK1)是IγB激酶发生磷酸化的重要调节因子，IKK使NF-κB的亚单位IKBα发生磷酸化，磷酸化的IKBα发生降解，而最后留下p65-p50二聚体，该二聚体然后转位到细胞核内与κB基因的增强子区域或与他的顺式作用序列结合。

The result expressed that under the concentration of 0.2mg/mL, the 6 compounds are all active to Sarcina lutea, ME-1, MT-6, MT-land MT-7 are active to Bacillus megaterium, to Escherichia coli, only MT-2 is active. The dimeric natural products are intensively existed in botany, most of them have the obvious biological activities. They have been concentrated on in recent years, and they are one of the compounds to which are enjoyed great popularity in natural product.

结果表明，在浓度为0.2mg/mL的条件下，六种化合物对藤黄八叠球菌均具有明显抑制作用，ME-1、MT-6、MT-1、MT-7对巨大芽孢杆菌有抑制作用，MT-2对大肠杆菌有抑制作用，对绿脓杆菌和枯草芽孢杆菌六种成分均无抑制作用；二聚体化合物在植物界广泛存在，多数二聚体天然产物具有显著的生物活性，引起人们的重视，是天然产物化学界研究的热门化合物之一。
