Abstract
An isolated endo-fucoidan-lyase is described. The enzyme acts on fucoidan, has a pH optimum from 6 to 10, and has an optimum pH from 30 to 40° C. The enzyme can be isolated from Flavobacterium sp. FERM BP-5402. The enzyme is used to obtain sugar compounds which are useful in the study on carbohydrates.
