IntEnz Enzyme Nomenclature
EC 3.2.1.181

Names

Accepted name:
galactan endo-β-1,3-galactanase
Other name:
endo-β-1,3-galactanase
Systematic name:
arabinogalactan 3-β-D-galactanohydrolase

Reaction

Comments:

The enzyme from the fungus Flammulina velutipes (winter mushroom) hydrolyses the β(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 β-1,3-residues. cf. EC 3.2.1.89, arabinogalactan endo-β-1,4-galactanase and EC 3.2.1.145, galactan 1,3-β-galactosidase.
