| 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. EC 3.2.1.55, non-reducing end α-L-arabinofuranosidase. |
