beta-L-arabinofuranoside non-reducing end beta-L-arabinofuranosidase

beta-L-arabinofuranosyl-(1->2)-beta-L-arabinofuranose + H2O = 2 beta-L-arabinofuranose [RN:R10346]

R10346
Reaction

beta-L-arabinofuranosyl-(1->2)-beta-L-arabinofuranose [CPD:C20568];
H2O [CPD:C00001]

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.
