Enzyme-catalyzed structural modification of natural product molecules Jiang Zhongyi (School of Chemical Engineering and Technology, Tianjin University, Tianjin 300072 ) Abstract Enzymatic reaction, as a green and novel approach with high efficiency, has found more and more applications in natural products molecule modification. This paper briefly addressed the enzyme-catalyzed modification of natural products molecules including sugars and glycosides, steroids, antibiotics, amino acids and polypeptides, as well as some bioconjugates. The development tendency concerning the enzyme-catalyzed modification of natural products was tentatively predicted.
