蜂毒素 meaning in Chinese
apitoxin
Examples
- We got some significant results regarding m - centrin by chemical methods . the titration of m - centrin by terbium ions was monitored by uv different spectrum and fluorescence spectrum
利用紫外光谱和荧光光谱的方法探讨了中心蛋白突变体和金属离子及蜂毒素之间的相互作用。 - Cationic antibacterial peptides are found in insect , animal and plant . they are grouped into four classes including cecropins , magainins , melittins and defensins . cema consists of eight amino acid from n - terminus of cecropin a and c - terminus of modified melittin
阳离子抗菌肽是一类广泛存在于昆虫、动物、植物体内的小分子抗菌活性多肽，大体可分为：杀菌肽( cecropin ) 、蛙皮素( magainin ) 、蜂毒素( melittin ) 、防御素( defensin )等四大类。 - Abstract : the effects of terbium ion on the conformation of calmodulin and on the interaction between calmodulin and melittin have been studied by the endogenous fluorescent spectrometry of calmodulin and melittin , and the sensitized fluorescent spectrometry of terbium ion , respectively . the results show that terbium ions have a tight binding site in the i and ii metal - binding sites of calmodulin . the conformation of calmodulin induced by terbium ion can bind melittin and transfer the tryptophane residue of melittin to a relatively hydrophobic environment , while the binding of melittin to calmodulin produces effect on the binding orders of terbium ion in camodulin . results from ft - ir spectrometry have revealed that upon binding of lanthanum ion , apo - calmodulin undergoes a conformational change with the increase of - helix content and the decrease of - sheet content . melittin ' s binding to calmodulin has no effect on its conformation induced by the binding of lanthanum ion to calmodulin
文摘:分别用钙调蛋白和蜂毒素的内源荧光光谱以及铽离子的敏化荧光光谱考察了铽离子对钙调蛋白构象变化以及对钙调蛋白与蜂毒素相互作用的影响.结果表明，铽离子首先结合在钙调蛋白的第和第位点，铽离子不影响钙调蛋白与蜂毒素的相互作用，蜂毒素与钙调蛋白作用后不影响铽离子在钙调蛋白上的键合顺序.傅里叶变换红外光谱结果表明三价的镧离子与钙调蛋白作用使钙调蛋白的螺旋结构增加，折叠结构减少，与钙离子对它的二级结构影响相类似.稀土离子在钙调蛋白-蜂毒素复合体系中主要与钙调蛋白作用
