The enzyme, which was identified in the bacterium Bifidobacterium longum JCM1217, removes the beta-L-arabinofuranose residue from the non-reducing end of multiple substrates, including beta-L-arabinofuranosyl-hydroxyproline (Ara-Hyp), Ara2-Hyp, Ara3-Hyp, and beta-L-arabinofuranosyl-(1->2)-1-O-methyl-beta-L-arabinofuranose.In the presence of 1-alkanols, the enzyme demonstrates transglycosylation activity, retaining the anomeric configuration of the arabinofuranose residue. cf. EC 3.2.1.55, non-reducing end alpha-L-arabinofuranosidase.
