ENZYME entry: EC 3.2.1.211

PURL: https://purl.expasy.org/enzyme/EC/3.2.1.211
Accepted Name
endo-(1->3)-fucoidanase
Alternative Name(s)
alpha-L-fucosidase
poly(1,3-alpha-L-fucoside-2/4-sulfate) glycanohydrolase
Reaction catalysed
endohydrolysis of (1->3)-alpha-L-fucoside linkages in fucan
Comment(s)
  • The enzyme specifically hydrolyzes (1->3)-alpha-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 alpha-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 alpha-L-fucopyranosyl residues may occur at positions 2 and 4.
  • The enzyme degrades fucan to sulfated alpha-L-fucooligosaccharides but neither L-fucose nor small fucooligosaccharides are produced.
  • Formerly EC 3.2.1.44.
