arabinogalactan 3-beta-D-galactanohydrolase

The enzyme specifically hydrolyses beta-1,3-galactan and beta-1,3-galactooligosaccharides

The enzyme from the fungus Flammulina velutipes (winter mushroom) hydrolyses the beta(1->3) bonds found in type II plant arabinogalactans, which occur in cell walls of dicots and cereals. The enzyme is an endohydrolase, and requires at least 3 contiguous beta-1,3-residues. cf. EC 3.2.1.89, arabinogalactan endo-beta-1,4-galactanase and EC 3.2.1.145, galactan 1,3-beta-galactosidase.
