In enzymology, enzymes that add a fructose group to a molecule are called fructosyl-transferases, beta-D-fructofuranosyl transferases or fructotranferases. Examples are:
* aldose beta-D-fructosyltransferase
* 2,1-fructan:2,1-fructan 1-fructosyltransferase
* 6G-fructosyltransferase
* Inulin fructotransferase (DFA-I-forming)
* Inulin fructotransferase (DFA-III-forming)
* Levan fructotransferase (DFA-IV-forming)
* Levansucrase
