Abstract: Oligosaccharide oxidase is a new type of oxidases, which  belongs to the auxiliary activity family 7 (AA7). It can catalyze various oligosaccharides into corresponding aldehyde acids and generate hydrogen peroxide in the reaction process. According to the substrates, the reported oligosaccharide oxidases are classed into gluco-oligosaccharide oxidase (GOOX), xylo-oligosaccharide oxidase (XOOX) and chito-oligosaccharide oxidase (COOX), etc. Oligosaccharide oxidase has a wide range of applications, and can be used in multiple fields such as food, medicine, feed, bio-fuel, and so on. However, few studies were carried out on oligosaccharide oxidase to present at home and abroad. Based on this situation, several aspects including enzymatic property, molecular structure, catalytic mechanism, molecular improvement and industrial application about oligosaccharide oxidase were reviewed in order to provide some insights into the research and application of oligosaccharide oxidase.

Key words: oligosaccharide oxidase, enzymatic properties, molecular improvement, structure and function
