DE   endo-(1->4)-fucoidanase.
AN   alpha-L-fucosidase.
AN   poly(1,4-alpha-L-fucoside-2/3-sulfate) glycanohydrolase.
CA   endohydrolysis of (1->4)-alpha-L-fucoside linkages in fucan.
CC   -!- The enzyme specifically hydrolyzes (1->4)-alpha-L-fucoside linkages
CC       in fucan.
CC   -!- Fucans are found mainly in different species of seaweed and are
CC       sulfated polysaccharides with a backbone of (1->3)-linked or
CC       alternating (1->3)- and (1->4)-linked alpha-L-fucopyranosyl residues.
CC   -!- In the literature, the sulfated polysaccharides are often called
CC       fucoidans.
CC   -!- Fucoidans include polysaccharides with a relatively low proportion of
CC       fucose and some polysaccharides that have a backbone composed of
CC       other saccharides with fucose in the branching side chains.
CC   -!- The sulfation of the alpha-L-fucopyranosyl residues may occur at
CC       positions 2 and 3.
CC   -!- The enzyme degrades fucan to sulfated alpha-L-fucooligosaccharides
CC       but neither L-fucose nor small fucooligosaccharides are produced.
CC   -!- Formerly EC 3.2.1.44.
