  3.2.1.211 | fucoidan + H2O |
fucoidan from Fucus gardneri. The fucoidanase hydrolyzes fucoidan without desulfation to form oligosaccharides ranging from 10 to 2 fucose units plus the monosaccharide, fucose. Fucose can not be detected until late in the hydrolysis period, and sulfate release is not detectable during the first 4 hours of fucoidanase action |

the enzyme can efficiently degrade the fucoidan of brown algae. The endo-type hydrolysis of fucoidan results in the formation of sulfated alpha-L-fucooligosaccharides. No production of mono- or disaccharides in noticeable amounts |

| 3.2.1.211 | fucoidan + H2O |
fucoidan from the brown alga Fucus distichus. The polysaccharide molecules include alternating residues of 3-linked alpha-L-fucopyranose sulfated at positions 2 and 4 and of 4-linked alpha-L-fucopyranose sulfated only at position 2. The enzyme cleaves some glycosidic bonds in fucoidan from the brown alga Fucus distichus, but neither fucose nor lower oligosaccharides are produced. The main product isolated from the incubation mixture is a polysaccharide built up of disaccharide repeating units (->3)-alpha-L-Fucp-(2,4-di-SO3-)-(1->4)-alpha-L-Fucp-(2SO3-)-(1->). A polymer fraction with the same carbohydrate chain but sulfated only at positions 2 and nonstoichiometrically acetylated at positions 3 and 4 of fucose residues is isolated as a minor component |
