IUBMB Enzyme Nomenclature


Accepted name: inulosucrase

Reaction: sucrose + [(2→1)-β-D-fructosyl]n = glucose + [(2→1)-β-D-fructosyl]n+1

Other name(s): sucrose 1-fructosyltransferase; sucrose:2,1-β-D-fructan 1-β-D-fructosyltransferase

Systematic name: sucrose:(2→1)-β-D-fructan 1-β-D-fructosyltransferase

Comments: Converts sucrose into inulin and D-glucose. Some other sugars can act as D-fructosyl acceptors.
