In [[enzymology]], an '''inulosucrase''' ({{EC number|2.4.1.9}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:sucrose + (2,1-beta-D-fructosyl)n <math>\rightleftharpoons</math> glucose + (2,1-beta-D-fructosyl)n<sup>+</sup>1

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[sucrose]] and [[(2,1-beta-D-fructosyl)n]], whereas its two [[product (chemistry)|products]] are [[glucose]] and [[(2,1-beta-D-fructosyl)n+1]].

This enzyme belongs to the family of [[glycosyltransferase]]s, specifically the hexosyltransferases.  The systematic name of this enzyme class is '''sucrose:2,1-beta-D-fructan 1-beta-D-fructosyltransferase'''. This enzyme is also called '''sucrose 1-fructosyltransferase'''.
