一种γ-谷氨酰转肽酶固定化酶及其制备方法和应用
摘要：
本发明公开了一种γ-谷氨酰转肽酶固定化酶，它包括酶、固定所述酶的载体和包覆材料，所述的酶为γ-谷氨酰转肽酶，所述的载体为镍亲和载体，所述的包覆材料为聚乙烯亚胺。本发明还公开了上述γ-谷氨酰转肽酶固定化酶的制备方法及其应用。本发明所得到的γ-谷氨酰转肽酶固定化酶具有制备简单快速、酶稳定性强、重复使用性能好等特点，为进一步提高γ-谷氨酰转肽酶的稳定性以适应工业化应用奠定基础。
摘要（英）：

The invention discloses a gamma-glutamyltranspeptidase immobilized enzyme which comprises an enzyme, a carrier for fixing the enzyme and a clad material, wherein the enzyme is a gamma-glutamyltranspeptidase, the carrier is a nickel affinity carrier, and the clad material is polyethylenimine. The invention further discloses a preparation method and an application of the gamma-glutamyltranspeptidase immobilized enzyme. The gamma-glutamyltranspeptidase immobilized enzyme has the advantages of being simple and rapid in preparation, high in stability, good in reuse performance and the like; and a foundation is laid for further improvement of the stability and adaptation to industrial application of the gamma-glutamyltranspeptidase.
