DE   arabinogalactan exo alpha-(1,3)-beta-L-arabinopyranosyl-(1->3)-L-
DE   arabinofuranosidase (non-reducing end).
AN   3-O-beta-L-arabinopyranosyl-alpha-L-arabinofuranosidase.
CA   Hydrolysis of beta-L-Arap-(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
CC       pseudocatenulatum, specifically hydrolyzes beta-L-Arap-(1->3)-L-Araf
CC       disaccharides from the non-reducing terminal of arabinogalactan using
CC       an exo mode of action. It is active with arabinogalactan-proteins
CC       (AGPs) containing type II arabinogalactans such as gum arabic AGP and
CC       larch AGP.
CC   -!- The enzyme can also hydrolyze alpha-D-Galp-(1->3)-L-Araf
CC       disaccharides (cf. EC 3.2.1.215) with a much lower activity.
