英文摘要：

Engineering and redesign of enzymes are important to industrial biocatalysis. Fusion enzyme technology, based on fusion protein design, is frequently used in multifunctional enzyme construction and enzyme proximity control. Here, we reviewed the recent progress in molecular design strategy and application studies of fusion enzymes. The concept and features of fusion enzymes were introduced, followed by a systematical summary of the design strategy of fusion enzymes. In particular, the effects of different linker properties on fusion enzymes and their possible mechanisms were discussed. In addition, recent studies on fusion enzyme applications were also discussed. Finally, based on our own studicson fusion enzymes and the current research progress, the key problems in fusion enzyme technology and perspectives of this field were discussed.
