Entry
EC 3.2.1.181                Enzyme                                 

Name
galactan endo-beta-1,3-galactanase;
endo-beta-1,3-galactanase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
BRITE hierarchy
Sysname
arabinogalactan 3-beta-D-galactanohydrolase
Reaction(IUBMB)
The enzyme specifically hydrolyses beta-1,3-galactan and beta-1,3-galactooligosaccharides
Comment
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.
