The immobilization of proteins on epoxy activated supports is discussed in this chapter. Immobilization on epoxy supports is carried out as a two-step mechanism: in the first step the adsorption of the protein is promoted and in the second step the intramolecular covalent linkage among epoxy groups and nucleophiles of the protein is produced. Based on this mechanism of the need of a first adsorption of the protein on the support, different epoxy supports are described. The different supports are able to immobilize proteins through different orientations being obtained catalysts with different properties of activity, stability, and selectivity.
本章讨论了蛋白质在环氧活化载体上的固定化。蛋白质在环氧载体上的固定化通过两步机制进行:第一步促进蛋白质的吸附,第二步在环氧基团与蛋白质的亲核试剂之间形成分子内共价键。基于蛋白质首先需要吸附在载体上这一机制,描述了不同的环氧载体。不同的载体能够通过不同的取向固定蛋白质,从而获得具有不同活性、稳定性和选择性的催化剂。
