• Development of Sulfhydryl-Reactive Silica for Protein Immobilization in High-Performance Affinity Chromatography
  作者：Rangan Mallik、Chunling Wa、David S. Hage

  Two techniques were developed for the immobilization of proteins and other ligands to silica through sulfhydryl groups. These methods made use of maleimide-activated silica (the SMCC method) or iodoacetyl-activated silica (the SIA method). The resulting supports were tested for use in high-performance affinity chromatography by employing human serum albumin (HSA) as a model protein. Studies with normal and iodoacetamide-modified HSA indicated that these methods had a high selectivity for sulfhydryl groups on this protein, which accounted for the coupling of 77−81% of this protein to maleimide- or iodoacetyl-activated silica. These supports were also evaluated in terms of their total protein content, binding capacity, specific activity, nonspecific binding, stability, and chiral selectivity for several test solutes. HSA columns prepared using maleimide-activated silica gave the best overall results for these properties when compared to HSA that had been immobilized to silica through the Schiff base method (i.e., an amine-based coupling technique). A key advantage of the supports developed in this work is that they offer the potential of giving greater site-selective immobilization and ligand activity than amine-based coupling methods. These features make these supports attractive in the development of protein columns for such applications as the study of biological interactions and chiral separations.

  研究人员开发了两种通过巯基将蛋白质和其他配体固定在二氧化硅上的技术。这两种方法分别利用马来酰亚胺活化二氧化硅（SMCC法）和碘乙酰活化二氧化硅（SIA法）。研究人员用人血清白蛋白（HSA）作为模型蛋白，测试了所得载体在高效亲和色谱法中的使用效果。对正常和碘乙酰胺修饰HSA的研究表明，这两种方法对蛋白质上的巯基具有高度选择性，可将77-81%的蛋白质与马来酰亚胺或碘乙酰活化二氧化硅偶联。研究人员还评估了这些载体的总蛋白含量、结合能力、特异性活性、非特异性结合、稳定性以及对几种测试溶质的立体选择性。与通过席夫碱法（一种基于胺的偶联技术）固定在二氧化硅上的HSA相比，用马来酰亚胺活化二氧化硅制备的HSA柱在这些特性上具有最佳的整体效果。这项工作中开发的载体的一个关键优势在于，它们具有比基于胺的偶联方法更高的位点选择性固定和配体活性。这些特性使这些载体在开发蛋白质色谱柱方面具有吸引力，可用于生物相互作用和手性分离等应用。

  measured. The three dimensional structures of trypsin-IAP and trypsin-IIAP were predicted by homology modeling, and the conserved residues required for functionality were identified. Two loops controlling the specificity of the trypsin and the substrate-binding pocket represented in the model are almost identical in primary sequences and backbone tertiary structures of the trypsin families.

  胰蛋白酶是通过破坏赖氨酸和精氨酸残基羧基侧的肽键，在动物蛋白消化中很重要的关键蛋白，因此已广泛用于各种生物技术过程中。在当前的研究中，从鸭（Anas platyrhynchos）中构建了一个容量为5·10（5）CFU / ml的全长cDNA文库。使用表达序列标签（EST）测序，鉴定出编码两个胰蛋白酶的基因，然后通过cDNA末端快速扩增（RACE）-PCR获得两个全长的胰蛋白酶cDNA。使用BlaST，它们被分类为胰蛋白酶I和II子家族，但是都编码位于C端的信号肽，激活肽和223-aa成熟蛋白。推导的两个成熟蛋白分别命名为胰蛋白酶-IAP和胰蛋白酶-IIAP，其理论等电点（pI）和分子量（MW）分别为7.99 / 23466.4 Da和4.65 / 24066.0 Da。基因的分子表征通过详细的生物信息学分析进一步进行。系统发育分析表明，胰蛋白酶-IIAP具有不同于胰蛋白酶-IAP的进化模式
