Non-reducing end alpha-L-arabinofuranosidase.

based on mapping to UniProt Q8NK89

Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.

-!- Acts on alpha-L-arabinofuranosides, alpha-L-arabinans containing (1,3)- and/or (1,5)-linkages, arabinoxylans and arabinogalactans. -!- Some EC 3.2.1.23 and EC 3.2.1.38 enzymes also hydrolyze alpha-L- arabinosides. -!- cf. EC 3.2.1.185. -!- Formerly EC 3.2.1.79.
