CC -!- FUNCTION: Glycoside hydrolase releasing xylosyl residues from
CC xyloglucan oligosaccharides at the non-reducing end. Has alpha-
CC xylosidase activity against xylan oligosaccharides. Also has alpha-
CC glucosidase activity against p-nitrophenyl-alpha-D-glucopyranoside. No
CC activity against p-nitrophenyl-D-xyloside.
CC {ECO:0000269|PubMed:11402218, ECO:0000269|PubMed:20801759,
CC ECO:0000269|PubMed:21170548}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of terminal, non-reducing alpha-D-xylose residues
CC with release of alpha-D-xylose.; EC=3.2.1.177;
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall. Secreted, extracellular
CC space, apoplast.
CC -!- TISSUE SPECIFICITY: Expressed in roots, stems, leaves, flowers and
CC siliques. Expressed in cell types undergoing cell wall modifications,
CC including trichomes, vasculature, stomata, and elongating anther
CC filaments. Not detected in pollen. {ECO:0000269|PubMed:16267099,
CC ECO:0000269|PubMed:20801759}.
CC -!- DEVELOPMENTAL STAGE: Expressed at higher levels in younger, faster
CC growing leaves than in older, slower growing leaves.
CC {ECO:0000269|PubMed:11402218}.
CC -!- DISRUPTION PHENOTYPE: No visible growth or morphological phenotypes,
CC with the exception of shorter siliques. Loss of alpha-xylosidase
CC activity and altered xyloglucan composition.
CC {ECO:0000269|PubMed:16267099, ECO:0000269|PubMed:20801759,
CC ECO:0000269|PubMed:21170548}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 31 family. {ECO:0000255}.
