EC 2.4.1.183     
Accepted name: α-1,3-glucan synthase
Reaction: UDP-glucose + [α-D-glucosyl-(1→3)]n = UDP + [α-D-glucosyl-(1→3)]n+1
Other name(s): uridine diphosphoglucose-1,3-α-glucan glucosyltransferase; 1,3-α-D-glucan synthase; UDP-glucose:α-D-(1-3)-glucan 3-α-D-glucosyltransferase
Systematic name: UDP-glucose:α-D-(1→3)-glucan 3-α-D-glucosyltransferase
Comments: A glucan primer is needed to begin the reaction, which brings about elongation of the glucan chains.
