Accepted name: |
non-reducing end β-L-arabinopyranosidase |
Reaction: |
Removal of a terminal β-L-arabinopyranose residue from the non-reducing end of its substrate. |
Other name(s): |
vicianosidase; β-L-arabinosidase (ambiguous); β-L-arabinoside arabinohydrolase (ambiguous) |
Systematic name: |
β-L-arabinopyranoside non-reducing end β-L-arabinopyranosidase |
Comments: |
The enzyme, which was characterized from dormant seeds of the plant Cajanus cajan (pigeon pea), has been shown to remove the terminal non-reducing β-L-arabinopyranoside residue from the artificial substrate p-nitrophenyl-β-L-arabinopyranose [1]. In the presence of methanol the enzyme demonstrates transglycosylase activity, transferring the arabinose moiety to methanol while retaining the anomeric configuration, generating 1-O-methyl-β-L-arabinopyranose [2]. |
