Protein
Sucrose:sucrose 1-fructosyltransferase
Organism
Festuca arundinacea
Function
Transferase involved in fructan biosynthesis that catalyzes the production of 1-kestose (fructose and nystose to a lower extent) from sucrose. Exhibits also some hydrolase activity toward 1-kestose, thus producing fructose and sucrose. A weak fructosyltransferase activity leads to the formation of nystose from 1-kestose.
Similarity
Belongs to the glycosyl hydrolase 32 family.
