Agave tequilana fructans |
3.2.1.153 | more |
Agave tequilana fructans are a polydisperse mixture of long degree of polymerization (DP) polymers and fructooligosaccharides (FOSs) with both b(2-1) and b(2-6) linkages. This mixture also contains highly branched agavins and graminans, and agavins are the most abundant of all. Agave tequilana fructans exhibit fluctuation of their total reducing sugar content and DP according to the plant age |

Bp1-FEHa is a fructan exohydrolase with predominant activity towards beta-2,1-linkages |
3.2.1.153 | more |
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 | more |
hydrolytic cleavage of terminal fructosyl residues off inulin |
3.2.1.153 | more |
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 | more |
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 | more |
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 |
