|
|
|
||
| UniProt code: Q45071. |
|
||
| Organism: | |
Bacillus subtilis (strain 168). |
| Taxonomy: | |
Bacteria; Firmicutes; Bacilli; Bacillales; Bacillaceae; Bacillus. |
|
||
|
||
| 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. {ECO:0000269|PubMed:17426966}. |
