RT arabinofuranosidase required for pectic arabinan modification in

CC -!- FUNCTION: Involved in pectic arabinan modification in mucilage
CC secretory cells. Acts also as a beta-D-xylosidase during the remodeling
CC of xylans in vascular development. {ECO:0000269|PubMed:12609041,
CC ECO:0000269|PubMed:15181203, ECO:0000269|PubMed:19458117}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside
CC residues in alpha-L-arabinosides.; EC=3.2.1.55;
CC Evidence={ECO:0000269|PubMed:15181203};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=1.2 mM for p-nitrophenyl-beta-D-xylopyranoside
CC {ECO:0000269|PubMed:15181203};
CC pH dependence:
CC Optimum pH is 4.9. {ECO:0000269|PubMed:15181203};
CC Temperature dependence:
CC Optimum temperature is 55 degrees Celsius.
CC {ECO:0000269|PubMed:15181203};
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in leaves, stems, seedlings, roots,
CC inflorescences, siliques and developing seeds. Expressed in the
CC vasculature of the roots, leaves, flowers and silique. Expressed in
CC tissues undergoing secondary cell wall thickening such as protoxylem,
CC metaxylem, intrafascicular cambium and fibers.
CC {ECO:0000269|PubMed:12609041, ECO:0000269|PubMed:15181203,
CC ECO:0000269|PubMed:19458117}.
CC -!- INDUCTION: By sugar starvation. {ECO:0000269|PubMed:17234672}.
CC -!- DISRUPTION PHENOTYPE: Delayed seeds germination resulting from an
CC altered mucilage composition. No visible growth defects; probably due
CC to partial redundancy with BXL2. Bxl1 and bxl2 double mutants have
CC shortened siliques and curled leaf edges.
CC {ECO:0000269|PubMed:19458117}.
CC -!- MISCELLANEOUS: Might be processed at the C-terminus.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 3 family. {ECO:0000305}.
