3.2.1.153 fructan + H2O Agave tequilana fructans 3.2.1.153 inulin + H2O - 3.2.1.153 additional information the enzyme is involved in fructan breakdown 3.2.1.153 additional information isoenzyme 1-FEH w2 might play a role as a beta-(2,1)-trimmer throughout the period of active graminan biosynthesis 3.2.1.153 additional information isoform 1-FEH II is expressed when young chicory plants are defoliated, suggesting that this enzyme can be induced at any developmental stage when large energy supplies are necessary 3.2.1.153 additional information the enzyme is involved in fructan degradation 3.2.1.153 additional information high expression level in conditions of active fructan synthesis, low expression level when fructan contents are low. The enzyme might play a role as a beta-(2,1) trimming enzyme acting during fructan synthesis in concert with fructan synthesis enzymes 3.2.1.153 additional information hydrolytic cleavage of terminal fructosyl residues off inulin 3.2.1.153 additional information Bp1-FEHa is a fructan exohydrolase with predominant activity towards beta-2,1-linkages 3.2.1.153 additional information isozyme Wfh-sm3m hydrolyzes beta-(2,6)-linkages of fructans (6-kestotriose) more efficiently than beta-(2,1)-linkages of fructans (1-kestotriose and 1,1-kestotetraose). On the other hand, Wfh-sm3m cannot hydrolyze long-chain fructans such as inulin and bacterial levan
