Accepted name: non-reducing end β-L-arabinofuranosidase
Reaction: β-L-arabinofuranosyl-(1→2)-β-L-arabinofuranose + H2O = 2 β-L-arabinofuranose
Other name(s): HypBA1
Systematic name: β-L-arabinofuranoside non-reducing end β-L-arabinofuranosidase
Comments: The enzyme, which was identified in the bacterium Bifidobacterium longum JCM1217, removes the β-L-arabinofuranose residue from the non-reducing end of multiple substrates, including β-L-arabinofuranosyl-hydroxyproline (Ara-Hyp), Ara2-Hyp, Ara3-Hyp, and β-L-arabinofuranosyl-(1→2)-1-O-methyl-β-L-arabinofuranose. In the presence of 1-alkanols, the enzyme demonstrates transglycosylation activity, retaining the anomeric configuration of the arabinofuranose residue. cf.
