Inulosucrase Explained

inulosucrase
Ec Number:	2.4.1.9
Cas Number:	9030-16-4
Go Code:	0047725

In enzymology, an inulosucrase 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.
