Beta-fructofuranosidase that can use sucrose and 1-kestose, and, to a lower extent, neokestose and levan, as substrates, but not inuline. Hydrolysis of terminal non-reducing beta-D-fructofuranoside residues in beta-D-fructofuranosides. Associated to the cell wall. A number of isoforms are produced. According to EST sequences. Expressed in seedlings, leaves, flowers, and seeds. By wounding, aeroponic growth condition, darkness, sucrose, glucose and mannitol. Belongs to the glycosyl hydrolase 32 family.
