Abstract:As a linear polysaccharide, alginate has different physiological and biochemical characteristics according to its structure and composition. It holds great application value and potential in food, medicine and cosmetics. These characteristics of alginate are mainly controlled by the action of alginate-modifying enzymes such as alginate lyase, mannuronan C5-epimerase, alginate acetylase and alginate deacetylase. This review mainly introduced the synthesis of alginate-modifying enzymes and the mechanism of alginate modification, and summarized the source, classification, structure, mode of action and research progress of several alginate modifying enzymes. The emphasis was laid on the research progress of alginate lyase and mannuronan C5-epimerase. And we also prospected the future development of related research, providing reference for the further development and application of alginate and its related modifying enzymes.
