ID 3.2.1.164 DE galactan endo-1,6-beta-galactosidase. AN endo-1,6-beta-galactanase. AN endo-beta-(1->6)-galactanase. CA Endohydrolysis of (1->6)-beta-D-galactosidic linkages in arabinogalactan CA proteins and (1->3):(1->6)-beta-galactans to yield galactose and beta- CA (1->6)-galactaobiose as the final products. CC -!- Specifically hydrolyzes 1,6-beta-D-galactooligosaccharides with a CC degree of polymerization (DP) higher than 3, and their acidic CC derivatives with 4-O-methylglucosyluronate or glucosyluronate groups CC at the non-reducing terminals. CC -!- 1,3-beta-D- and 1,4-beta-D-galactosyl residues cannot act as CC substrates. CC -!- Can also hydrolyze alpha-L-arabinofuranosidase-treated CC arabinogalactan protein (AGP) extracted from radish roots. CC -!- AGPs are thought to be involved in many physiological events, such as CC cell division, cell expansion and cell death. DR Q76FP5, 6GAL_HYPRU ; //
