[[http://www.uniprot.org/uniprot/REOX_BACHD REOX_BACHD]] Hydrolyzes xylooligosaccharides with a degree of polymerization of greater than or equal to 3, releasing xylose from the reducing end. Only hydrolyzes the beta anomers of xylooligosaccharides, with inversion of anomeric configuration. Hydrolyzes the glucose and xylose-based trisaccharides where xylose is located at the -1 subsite, GXX, XXG and GXG. Does not hydrolyze xylan, chitosan, lichenan, curdlan or carboxymethylcellulose.<ref>PMID:15491996</ref>
