摘　　要：Silk fibroin can be widely used in textile industry,medical and clinical fields,owing to its good biocompatibility,mechanical and physiological properties.Enzymatic modification of silk fibroins allows processing under mild conditions,offering a safer and cleaner alternative.Polyphenol oxidases(tyrosinase,laccase)can catalyze the oxidation of the phenolic hydroxyl group in tyrosine residues ofSilk fibroin can be widely used in textile indus- try, medical and clinical fields, owing to its good bio- compatibility, mechanical and physiological proper- ties. Enzymatic modification of silk fibroins allows processing under mild conditions, offering a safer and cleaner alternative. Polyphenol oxidases （tyrosi- nase, laccase） can catalyze the oxidation of the phe- nolic hydroxyl group in tyrosine residues of fibroin proteins. These reactive groups that generated from enzymatic oxidation might further couple with amines, amino acids, and other amino-containing compounds, which provides a potential bio-method for functionalization of fibroin materials. In our re- cent work, we demonstrated that enzymatic incuba- tion with a mushroom tyrosinase evidently impacted the structure of silk fibroins, and led to a noticeable change in the properties of the fibroin materials.
