The results of its intrinsic fluorescence spectroscopy and fluorescence phase diagram showed that when the guanidine hydrochloride concentration in denaturation solution was about 1.0 mol/L, there existed a partially folded intermediate of Bacillus amyloliquefaciens a-amylase during its unfolding procedure, which followed a three-state model; the result of its fluorescence probe showed that when the guanidine hydrochloride concentration in denaturation solution was about 1.0 mol/L, there existed some stable hydrophobic regions, which could interact with a hydrophobic reagent 8-anilino-1-naphthalene sulfonic acid, in the partially folded intermediate of Bacillus amyloliquefaciens a-amylase; and the results of fluorescence quenching using acrylamide and potassium iodide as quenchers showed the distribution of Trp residues in Bacillus amyloliquefaciens a-amylase in different denaturation solution, with the maximum number (8) of tryptophan residues in a partially folded intermediate Bacillus amyloliquefaciens a-amylase molecule could be quenched by potassium iodide; and the results of their protein electrophoresis and SEC showed that no aggregate or aggregate precipitation of Bacillus amyloliquefaciens a-amylase formed during the whole unfolding procedure of Bacillus amyloliquefaciens a-amylase induced by guanidine hydrochloride.

内源荧光光谱和荧光相图结果表明，当变性液中盐酸胍浓度约为1.0 mol/L时，芽孢杆菌a-淀粉酶的去折叠过程中出现一个部分折叠中间体，其去折叠过程符合&三态模型&；荧光探针结果表明，在溶液中盐酸胍浓度约为1.0 mol/L时，中间态芽孢杆菌a-淀粉酶分子中存在着能够与探针分子1-苯胺基-8-萘磺酸结合的稳定的疏水区域；荧光猝灭研究给出了不同程度变性的淀粉液化芽孢杆菌a-淀粉酶中的Trp的分布情况，结果表明中间态芽孢杆菌a-淀粉酶分子中能够被碘化钾猝灭的位于分子表面的色氨酸残基数目达到最大的8个；蛋白电泳和体积排阻色谱结果表明，在盐酸胍诱导的芽孢杆菌a-淀粉酶分子的整个去折叠过程中，不会以共价键或非共价键形式形成芽孢杆菌a-淀粉酶分子之间的集聚体或集聚体沉淀。

Sodium malate and 1-Naphthyl phosphoric acid sodium were used as substrates. NBT and fast blue RR salt were used to stain MDH and ALP respectively.

鄄萘磷酸钠盐为特异性底物，氯化硝基四氮唑蓝和固蓝RR盐为染色剂，分别对MDH和ALP染色，以相对迁移率标记酶带。

In this dissertation, a kind of MPc and five metallonaphthalocyanine were synthesized. The molecular structure of the compounds were characterized by means of the elemental analysis, the infrared spectrum and the nuclear magnetic resonance spectrum, which proved that the topical compounds were successfully synthesized.
