additional information Agave tequilana 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 ?

General Information

General Information Comment Organism
metabolism proposed model for the biosynthesis of fructooligosaccharides (FOSs) in Agave tequilana Weber Blue variety, overview Agave tequilana
physiological function fructan metabolism in Agave tequilana exhibits changes in fructan content, type, degree of polymerization (DP), and molecular structure, overview. Analysis of the specific activities of involved vacuolar fructan active enzymes (FAZY) in Agave tequilana plants of different age and the biosynthesis of fructooligosaccharides (FOSs). Fructan hydrolysis is carried out by FEH enzymes, that remove terminal fructosyl units from fructan chains, to fulfill a diverse set of functions in the plant, such as energy supply during plant growth, maintenance of the osmotic pressure in the vacuoles, and modulation of the oligofructans amounts under oxidative stress and freezing tolerance Agave tequilana
