3.2.1.213 (1->6)-beta-D-galactooligosaccharide + H2O degradative enzyme for type II arabinogalactan side chains in cooperation with exo-beta-1,3-galactanase. The enzyme, characterized from the bacterium Bifidobacterium longum, specifically hydrolyses (1->6)-beta-galactobiose from the non-reducing terminal of (1->6)-beta-D-galactooligosaccharides with a degree of polymerization of 3 or higher, using an exo mode of action. The enzyme cannot hydrolyse alpha-L-arabinofuranosylated (1->6)-beta-galactans (as found in arabinogalactans) and does not act on (1->3)-beta-D- or (1->4)-beta-D-galactans 448357 3.2.1.213 (1->6)-beta-D-galactooligosaccharide + H2O the enzyme, characterized from the bacterium Bifidobacterium longum, specifically hydrolyses (1->6)-beta-galactobiose from the non-reducing terminal of (1->6)-beta-D-galactooligosaccharides with a degree of polymerization of 3 or higher, using an exo mode of action.
