ENZYME entry: EC 3.2.1.164

Accepted Name
Galactan endo-1,6-beta-galactosidase.
Alternative Name(s)
Endo-1,6-beta-galactanase.
Endo-beta-(1->6)-galactanase.
Reaction catalysed
Endohydrolysis of (1->6)-beta-D-galactosidic linkages in arabinogalactan proteins and (1->3):(1->6)-beta-galactans to yield galactose and beta-(1->6)-galactaobiose as the final products
Comment(s)
  • Specifically hydrolyzes 1,6-beta-D-galactooligosaccharides with a degree of polymerization (DP) higher than 3, and their acidic derivatives with 4-O-methylglucosyluronate or glucosyluronate groups at the non-reducing terminals.
  • 1,3-beta-D- and 1,4-beta-D-galactosyl residues cannot act as substrates.
  • Can also hydrolyze alpha-L-arabinofuranosidase-treated arabinogalactan protein (AGP) extracted from radish roots.
  • AGPs are thought to be involved in many physiological events, such as cell division, cell expansion and cell death.
