| Research Abstract |
Herbivorous marine gastropods like abalone and sea hare possess various polysaccharide-degrading enzymes which can degrade seaweeds' polysaccharides such as alginate, laminaran, mannan, xylane, and cellulose to oligo- and monosaccharides. These saccharides are considered to be metabolized via glycolytic pathway and TCA cycle. In the present study, we isolated several polysaccharide-degrading enzymes, e.g., alginate lyase, laminarinase and mannanase, from abalone and sea hare and investigated their biological roles in the metabolism of seaweeds' polysaccharides in gastropods.
