Sucrose-phosphate synthase
- Sucrose-phosphate synthase
In enzymology, a sucrose-phosphate synthase (EC number|2.4.1.14) is an enzyme that catalyzes the chemical reaction
:UDP-glucose + D-fructose 6-phosphate UDP + sucrose 6-phosphate
Thus, the two substrates of this enzyme are UDP-glucose and D-fructose 6-phosphate, whereas its two products are UDP and sucrose 6-phosphate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:D-fructose-6-phosphate 2-alpha-D-glucosyltransferase. Other names in common use include UDP-glucose-fructose-phosphate glucosyltransferase, sucrosephosphate-UDP glucosyltransferase, UDP-glucose-fructose-phosphate glucosyltransferase, SPS, uridine diphosphoglucose-fructose phosphate glucosyltransferase, sucrose 6-phosphate synthase, sucrose phosphate synthetase, and sucrose phosphate-uridine diphosphate glucosyltransferase. This enzyme participates in starch and sucrose metabolism.
