EC Tree
IUBMB Comments
The enzyme acts on alpha-L-arabinofuranosides, alpha-L-arabinans containing (1,3)- and/or (1,5)-linkages, arabinoxylans and arabinogalactans. Some beta-galactosidases (EC 3.2.1.23) and beta-D-fucosidases (EC 3.2.1.38) also hydrolyse alpha-L-arabinosides. cf. EC 3.2.1.185, non-reducing end beta-L-arabinofuranosidase.
