In enzymology, a sucrose synthase (EC2.4.1.13) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are NDP-glucose and D-fructose, whereas its two products are NDP and sucrose.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is NDP-glucose:D-fructose 2-alpha-D-glucosyltransferase. Other names in common use include UDPglucose-fructose glucosyltransferase, sucrose synthetase, sucrose-UDP glucosyltransferase, sucrose-uridine diphosphate glucosyltransferase, and uridine diphosphoglucose-fructose glucosyltransferase. This enzyme participates in starch and sucrose metabolism.
