In enzymology, an isomaltulose synthase (EC 5.4.99.11) is an enzyme that catalyzes the chemical reaction
sucroseHence, this enzyme has one substrate, sucrose, and one product, 6-O-Alpha-D-Glucopyranosyl-D-Fructofuranose.
This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring other groups. The systematic name of this enzyme class is sucrose glucosylmutase. Other names in common use include isomaltulose synthetase, sucrose alpha-glucosyltransferase, and trehalulose synthase.
Structural studies
As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1M53, 1ZJA, 1ZJB, 2PWD, 2PWE, 2PWF, and 2PWG.
