DE   arabinogalactan exo alpha-(1,3)-alpha-D-galactosyl-(1->3)-L-
DE   arabinofuranosidase (non-reducing end).
AN   3-O-alpha-D-galactosyl-alpha-L-arabinofuranosidase.
CA   Hydrolysis of alpha-D-Galp-(1->3)-L-Araf disaccharides from non-reducing
CA   terminals in branches of type II arabinogalactan attached to proteins.
CC   -!- The enzyme, characterized from the bacterium Bifidobacterium longum,
CC       specifically hydrolyzes alpha-D-Galp-(1->3)-L-Araf disaccharides from
CC       the non-reducing terminal of arabinogalactan using an exo mode of
CC       action.
CC   -!- It is particularly active with gum arabic arabinogalactan, a type II
CC       arabinogalactan produced by acacia trees.
CC   -!- The enzyme can also hydrolyze beta-L-Arap-(1->3)-L-Araf
CC       disaccharides, but this activity is significantly lower.
