In enzymology, a 2,1-fructan:2,1-fructan 1-fructosyltransferase (EC 2.4.1.100) is an enzyme that catalyzes the chemical reaction
- [beta-D-fructosyl-(2->1)-]m + [beta-D-fructosyl-(2->1)-]n [math]\displaystyle{ \rightleftharpoons }[/math] [beta-D-fructosyl-(2->1)-]m-1 + [beta-D-fructosyl-(2->1)-]n+1
Thus, the two substrates of this enzyme are [beta-D-fructosyl-(2->1)-m]] and beta-D-fructosyl-(2->1)-n]], whereas its two products are beta-D-fructosyl-(2->1)-m-1]] and beta-D-fructosyl-(2->1)-n+1]].
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 2,1-beta-D-fructan:2,1-beta-D-fructan 1-beta-D-fructosyltransferase. Other names in common use include 1,2-beta-D-fructan 1F-fructosyltransferase, fructan:fructan fructosyl transferase, FFT, 1,2-beta-fructan 1F-fructosyltransferase, 1,2-beta-D-fructan:1,2-beta-D-fructan, 1F-beta-D-fructosyltransferase, and fructan:fructan 1-fructosyl transferase.
