The existence of dextran sulphate to the native ovalbumin leads to decrease about 60％ in fluorescence intensity following high pressure treatment. Complexation of polysaccharide with ovalbumin seems to protect the protein against pressure induced conformational change and aggregation; The presence of τ-carrageenan in glycinin solution is also found to protect the protein against pressure.

经超高压处理后，加入硫酸右旋糖苷的鸡蛋清蛋白溶液中的ANS荧光强度显著降低，降低约60％；这表明，硫酸右旋糖苷的加入可以和鸡蛋清蛋白相互作用，从而在超高压处理中起到稳定蛋白质天然构象的作用；对于大豆豆球蛋白溶液而言，ι-角叉菜胶的加入有维持高压下大豆豆球蛋白构象稳定性的作用。

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。

These compounds are of substantial interest both inviewpoints of theory and practical applications, mainlyunder the stimulus to achieve synthetic models either foractive sites of iron-sulfur proteins or for transitionmetal catalysts. This thesis describes the synthesis, structures andconformations of 51 new iron-sulfur cluster complexes,which have been characterized by elemental analysis andstandard spectroscopic methods. In addition, single-crystalX-ray diffraction analyses were performed for 4 representa-tive new compounds. Reactivities of μ-〓 with mono- and di- Grig-nard reagents derived intermediates toward various organicelectrophilic substrates were studied, along with complexa-tion of arynyl-containing iron-sulfur clusters by 〓Thus, several bridged, non-bridged, monomeric, dimeric,homonuclear, heteronuclear iron-sullfur and iron-sulfur co-balt-carbon cluster complexes were synthesized. A novelreaction and convenient route for the synthesis in highyield of tetranuclear iron complexes 〓 containing atetracoordinated sulfur atom was discovered, whereas aplausible mechanism based on experimental results was propo-sed for the formation of the new cluster type.
