ENZYME entry: EC 3.2.1.187

Accepted Name
(Ara-f)(3)-Hyp beta-L-arabinobiosidase.
Alternative Name(s)
Beta-L-arabinobiosidase.
Reaction catalysed
4-O-(beta-L-arabinofuranosyl-(1->2)-beta-L-arabinofuranosyl-(1->2)-beta-L-arabinofuranosyl)-(2S,4S)-4-hydroxyproline + H(2)O <=> 4-O-(beta-L-arabinofuranosyl)-(2S,4S)-4-hydroxyproline + beta-L-arabinofuranosyl-(1->2)-beta-L-arabinofuranose
Comment(s)
  • The enzyme, which was identified in the bacterium Bifidobacterium longum JCM1217, is specific for (Ara-f)(3)-Hyp, a sugar chain found in hydroxyproline-rich glyoproteins such as extensin and lectin.
  • The enzyme was not able to accept (Ara-f)(2)-Hyp or (Ara-f)(4)-Hyp as substrates.
  • In the presence of 1-alkanols, the enzyme demonstrates transglycosylation activity, retaining the anomeric configuration of the arabinofuranose residue.
