摘　　要：针对目前国内外关于嗜热麦芽糖转葡萄糖基酶的制备及应用进展进行了综述:主要采用基因克隆至常温宿主细胞中,通过宿主细胞的过量表达来完成制备,其应用主要体现在淀粉的优化改性、大环糊精的制备以及功能成分的糖基化修饰等方面.未来研究将集中于酶的多功能催化机制,同时拓展糖基化改性功能成分的种类及转糖基类型.The production of amylomahases and its promising applications were reviewed. The preparation was carried out through gene cloning to normal temperature host cell and the host cell excessive expression and the application reflected in modification of starches, production of large-ring cyclodextrins and transgly- cosylation of some functional ingredients, etc. It was further pointed out that the future research will focuse on multifunctional catalytic mechanism of the enzyme and increasing the varieties of glycosylation reactions as well as their functonal products.
