Abstract
Fucoidanase is a class of enzymes capable of hydrolyzing fucoidan, a complex sulfated polysaccharide found mainly in marine brown algae and some marine invertebrates. Fucoidan (FUC) has a wide range of potential health benefits and therapeutic effects, including antitumor, immunomodulatory, antiviral, and hypoglycemic activities. Fucoidanase can hydrolyze high-molecular-weight fucoidan into medium- and low-molecular-weight fucoidan. The low-molecular-weight fucoidan not only has good solubility, low viscosity, and high absorption rate but also retains the original biological activities of fucoidan. Fucoidanase has received much attention in recent years. This paper reviews the taxonomic origin, structure, enzymatic properties, and applications of fucoidanase to provide a reference for the study of fucoidanase.
