In enzymology, a sucrose:sucrose fructosyltransferase (EC 2.4.1.99) is an enzyme that catalyzes the chemical reaction
- 2 sucrose D-glucose + beta-D-fructofuranosyl-(2→1)-beta-D-fructofuranosyl alpha-D-glucopyranoside
Hence, this enzyme has one substrate, sucrose, but 2 products: D-glucose and beta-D-fructofuranosyl-(2→1)-beta-D-fructofuranosyl alpha-D-glucopyranoside.
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.
