Sucrose:sucrose fructosyltransferase (EC 2.4.1.99) is an enzyme that catalyzes the chemical reaction
-sucrose.svg.png)
The enzyme converts two units of its substrate, sucrose, into D-glucose and the trisaccharide, 1-kestose. It has been characterised from onion (Allium cepa)[1] and tall fescue (Lolium arundinaceum).[2] The product is a fructooligosaccharide.[3]
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is sucrose:sucrose 1'-beta-D-fructosyltransferase. Other names in common use include SST, sucrose:sucrose 1-fructosyltransferase, sucrose-sucrose 1-fructosyltransferase, sucrose 1F-fructosyltransferase, and sucrose:sucrose 1F-beta-D-fructosyltransferase.[4]
