KEGG   ENZYME: 3.2.1.145
Entry
EC 3.2.1.145                Enzyme                                 
Name
galactan 1,3-beta-galactosidase;
galactan (1->3)-beta-D-galactosidase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
galactan 3-beta-D-galactosidase
Reaction(IUBMB)
Hydrolysis of terminal, non-reducing beta-D-galactose residues in (1->3)-beta-D-galactopyranans
Comment
This enzyme removes not only free galactose, but also 6-glycosylated residues, e.g., (1->6)-beta-D-galactobiose, and galactose bearing oligosaccharide chains on O-6. Hence, it releases branches from [arabino-galacto-(1->6)]-(1->3)-beta-D-galactans.
