Sucrose:sucrose fructosyltransferase

In enzymology, a sucrose:sucrose fructosyltransferase is an enzyme that catalyzes the chemical reaction


 * 2 sucrose $$\rightleftharpoons$$ 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.
