ENTRY       EC 5.4.99.11
NAME        Isomaltulose synthase
            Sucrose glucosylmutase
CLASS       Isomerases
            Intramolecular transferases (mutases)
            Transferring other groups
SYSNAME     Sucrose glucosylmutase
REACTION    Sucrose = 6-O-alpha-D-Glucopyranosyl-D-fructofuranose
SUBSTRATE   Sucrose
PRODUCT     6-O-alpha-D-Glucopyranosyl-D-fructofuranose
            Isomaltose
COMMENT     The enzyme simultaneously produces isomaltulose
            (6-O-alpha-D-glucopyranosyl-D-fructose) and smaller amounts of
            trehalulose (1-O-alpha-D-glucopyranosyl-beta-D-fructose)
            from sucrose.
