General annotation (Comments)

Function

Alpha-L-arabinofuranosidase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose. Releases L-arabinose from arabinoxylan By similarity.

Catalytic activity

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

Subcellular location

Secreted Ref.1.

Sequence similarities

Belongs to the glycosyl hydrolase 62 family.
