Function

HYBA2_BIFL2 Beta-L-arabinobiosidase that removes L-arabinofuranose-beta-1,2-L-arabinofuranose disaccharide from various substrates such as carrot extensin and potato lectin. Also acts on L-arabinofuranose (Ara)-beta-1,2-Ara-beta-1,2-Ara-beta-Hyp (Ara(3)-Hyp) but not on Ara-beta-1,3-Ara-beta-1,2-Ara-beta-1,2-Ara-beta--Hyp (Ara(4)-Hyp) or Ara-beta-1,2-Ara-beta-Hyp (Ara(2)-Hyp), suggesting a specificity for unmodified Ara(3)-Hyp substrate. In the presence of 1-alkanols, shows transglycosylation activity, retaining the anomeric configuration of the arabinofuranose residue.^[1]
