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.
