| Abstract: | In this paper, the progress of thermostable glycosidases in recent years has been summarized in detail, including the current state of cloning and expression of glycosidases and applications in enzymatic synthesis of glycosidic compounds.The methods of improving the efficiency of transglycosylation, such as site directed mutagenesis, rational design of solution system and microwave radiation, have also been comparatively analyzed.With the high thermostability, thermostable glycosidases are expected to be a highly efficient and stable tool enzyme in the industrial production of glycoside compounds for hydrolysis and synthesis. |
