EC 3.2.1.212

Accepted name: endo-(1→4)-fucoidanase

Reaction: endohydrolysis of (1→4)-α-L-fucoside linkages in fucan

Other name(s): α-L-fucosidase (incorrect); poly(1,4-α-L-fucoside-2/3-sulfate) glycanohydrolase

Systematic name: poly[(1→4)-α-L-fucoside-2/3-sulfate] glycanohydrolase

Comments: The enzyme specifically hydrolyses (1→4)-α-L-fucoside linkages in fucan. Fucans are found mainly in different species of seaweed and are sulfated polysaccharides with a backbone of (1→3)-linked or alternating (1→3)- and (1→4)-linked α-L-fucopyranosyl residues. In the literature, the sulfated polysaccharides are often called fucoidans. Fucoidans include polysaccharides with a relatively low proportion of fucose and some polysaccharides that have a backbone composed of other saccharides with fucose in the branching side chains. The sulfation of the α-L-fucopyranosyl residues may occur at positions 2 and 3. The enzyme degrades fucan to sulfated α-L-fucooligosaccharides but neither L-fucose nor small fucooligosaccharides are produced.
