查询词典 complex

Correlation coefficient: 0.9962 . Positively charged'free'complex ions should be readily quenched by 〓, but when it is bound to DNA, it can be protected from the quencher because the highly negatively charged 〓 would be repelled by the negative DNA phosphated backbone, hindering quenching of the emission of the bound complex.

从理论上讲，带正电的配合物的阳离子应该可以被大阴离子淬灭，但是在DNA存在下，金属配合物插入到DNA的碱基对中，而〓被带负电荷的DNA磷酸骨架强烈排斥，从而避免了〓的淬灭，因此大的Stern-Volmer曲线斜率相应于对配合物较弱的保护形式。D。

It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.

在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中，我们发现，除非过量，否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象；过量的La〓（La〓/CaM摩尔比＞4）将引起钙调蛋白结合功能的下降，同时明显改变金属-钙调蛋白-Mas三元复合物的构象；La〓对Ca〓CaM-Mas的N末端表现高度选择性，显示了在三元复合物中两种离子间的协同效应；在三元体系中，La〓与钙调蛋白的亲和力明显上升，而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异，显示了作用的选择性；Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序，La〓很可能优先与C末端结合，从而使Mas/Mas X首先与C末端结合，该顺序与钙离子相同；La〓的参与使三元复合物在动力学上更加稳定。
