ENZYME entry: EC 3.2.1.215

PURL: https://purl.expasy.org/enzyme/EC/3.2.1.215
Accepted Name
arabinogalactan exo alpha-(1,3)-alpha-D-galactosyl-(1->3)-L- arabinofuranosidase (non-reducing end)
Alternative Name(s)
3-O-alpha-D-galactosyl-alpha-L-arabinofuranosidase
Reaction catalysed
Hydrolysis of alpha-D-Galp-(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 longum, specifically hydrolyzes alpha-D-Galp-(1->3)-L-Araf disaccharides from the non-reducing terminal of arabinogalactan using an exo mode of action.
  • It is particularly active with gum arabic arabinogalactan, a type II arabinogalactan produced by acacia trees.
  • The enzyme can also hydrolyze beta-L-Arap-(1->3)-L-Araf disaccharides, but this activity is significantly lower.
