资源简介：
The immobilization of thermostable GH3 β-glycosidase (Tpebgl3) was obtained by using NKA-9 macroporous resin modified with PEI and glutaraldehyde. The properties of NKA-9II, including thermal stability, pH stability, reusability, and tolerance of glucose, were greatly improved compared with free Tpebgl3. Moreover, this manuscript provides the first report that the coordinating metal cation Zn2+ enabled an immobilized enzyme to exhibit higher catalytic efficiency. Meanwhile, the addition of Zn2+ could greatly advance the reusability, thermostability, and glucose tolerance of NKA-9II compared with that with free metal ion, which is extremely beneficial for industrial applications.
