Alpha-1,3-glucan synthase
In enzymology, an alpha-1,3-glucan synthase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are UDP-glucose and n, whereas its two products are UDP and n+1.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:alpha-D--glucan 3-alpha-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-1,3-alpha-glucan glucosyltransferase, and 1,3-alpha-D-glucan synthase.
