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. Ref.1
Catalytic activity	Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
Subcellular location	Secreted By similarity.
Sequence similarities	Belongs to the glycosyl hydrolase 62 family.
