General annotation (Comments)

Function

Alpha-L-arabinofuranosidase involved in the degradation of arabinoxylan, a major component of plant hemicellulose. Able to hydrolyze 1,5-, 1,3- and 1,2-alpha-linkages not only in L-arabinofuranosyl oligosaccharides, but also in polysaccharides containing terminal non-reducing L-arabinofuranoses in side chains, like L-arabinan, arabinogalactan and arabinoxylan By similarity.

Catalytic activity

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

Pathway

Glycan metabolism; L-arabinan degradation.

Subcellular location

Secreted By similarity.

Domain

Organized into two domains: an N-terminal catalytic domain and a C-terminal arabinose-binding domain (ABD) By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 54 family.
