CC -!- FUNCTION: 6 and 1-fructan exohydrolase that can degrade both inulin and
CC levan-type fructans, such as phlein, levan, neokestose, levanbiose, 6-
CC kestose, 1-kestose, inulin, and 1,1-nystose. {ECO:0000269|Ref.5}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of terminal, non-reducing (2->1)- and (2->6)-linked
CC beta-D-fructofuranose residues in fructans.; EC=3.2.1.80;
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, apoplast
CC {ECO:0000305}. Secreted, cell wall {ECO:0000305}. Note=Associated to
CC the cell wall. {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q8W4S6-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q8W4S6-2; Sequence=VSP_035148;
CC -!- TISSUE SPECIFICITY: Expressed in seedlings and leaves, and, to a lower
CC extent, in flowers and seeds. {ECO:0000269|PubMed:12508063}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 32 family. {ECO:0000305}.
CC -!- CAUTION: Seems to not have any beta-fructofuranosidase activity.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAB87665.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
