General annotation (Comments)

Function

Cleaves arabinose units from O-2- or O-3-monosubstituted xylose residues, thereby assisting in arabinoxylan (AX) and short-chain arabinoxylo-oligosaccharide (AXOS) degradation. Is more active on wheat bran AXOS than on wheat water-extractable AX and rye water-extractable AX. Does not display endoxylanase, xylosidase or arabinanase activity. Ref.2

Catalytic activity

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

Pathway

Glycan degradation; xylan degradation.

Subcellular location

Secreted.

Domain

The CBM6 domain lost its carbohydrate binding capacity.

Sequence similarities

Belongs to the glycosyl hydrolase 43 family.

Contains 1 CBM6 (carbohydrate binding type-6) domain.

biophysicochemical properties

pH dependence:

Optimum pH is 5.6. Stable from pH 4.4 to 7.6.

Temperature dependence:

Optimum temperature is 45 degrees Celsius. Thermostable for 40 min from 4 to 45 degrees Celsius.

Mass spectrometry

Molecular mass is 52080 Da from positions 27 - 513. Determined by MALDI. Ref.2
