| 3.2.1.80 | physiological function |
the enzyme is involved in the complex regulation of fructan breakdown in defoliated grassland species, which is a major forage grass species and accumulates fructans, mainly composed of beta(2,6)-linked fructose units. Fructans are mobilized through strongly increased activities of fructan exohydrolases |

| 3.2.1.80 | physiological function |
the third member of the Ht1-FEH family in Jerusalem artichoke, i.e., Ht1-FEH III, not only demonstrates hydrolysis activity towards beta-(2->1)-linked fructans and beta-(2->6)-linked levan, but also towards sucrose |

AoEH4b contains three important amino acid residues, Asp57, Asp182, and Glu236 that are essential for enzymatic reaction catalysis and are conserved in the GH32 family |

| 3.2.1.80 | physiological function |
unlike other 1-FEHs, the enzyme shows minimal hydrolysis of 1-kestose but efficiently hydrolyzes neokestose and inulin-type fructans. The carbohydrates in storage Asparagus officinalis roots are inulin- and inulin neoseries-type fructans |
