    Functioni

    Has a 1.6-fold higher activity as an arabinosidase than as a beta-xylosidase when tested on the substrates nitrophenyl-beta-D-xylopyranoside and P-nitrophenyl-alpha-L-arabinofuranoside.

    Catalytic activityi

    Hydrolysis of (1->4)-beta-D-xylans, to remove successive D-xylose residues from the non-reducing termini.
    Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
