Inulosucrase

From Wikipedia, the free encyclopedia

In enzymology, an inulosucrase (EC 2.4.1.9) is an enzyme that catalyzes the chemical reaction

sucrose + (2,1-beta-D-fructosyl)n $\rightleftharpoons$ glucose + (2,1-beta-D-fructosyl)n⁺1

Thus, the two substrates of this enzyme are sucrose and (2,1-beta-D-fructosyl)n, whereas its two products are glucose and (2,1-beta-D-fructosyl)n+1.

This enzyme belongs to the family of glycosyltransferases, 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.
