ENZYME entry: EC 3.2.1.223

Accepted Name
arabinogalactan exo alpha-(1,3)-beta-L-arabinopyranosyl-(1->3)-L- arabinofuranosidase (non-reducing end)
Alternative Name(s)
3-O-beta-L-arabinopyranosyl-alpha-L-arabinofuranosidase
Reaction catalysed
Hydrolysis of beta-L-Arap-(1->3)-L-Araf disaccharides from non-reducing terminals in branches of type II arabinogalactan attached to proteins
Comment(s)
  • The enzyme, characterized from the bacterium Bifidobacterium pseudocatenulatum, specifically hydrolyzes beta-L-Arap-(1->3)-L-Araf disaccharides from the non-reducing terminal of arabinogalactan using an exo mode of action. It is active with arabinogalactan-proteins (AGPs) containing type II arabinogalactans such as gum arabic AGP and larch AGP.
  • The enzyme can also hydrolyze alpha-D-Galp-(1->3)-L-Araf disaccharides (cf. EC 3.2.1.215) with a much lower activity.
