ID 2.4.1.362 DE alpha-(1->3) branching sucrase. AN branching sucrase A. AN BRS-A. CA sucrose + a (1->6)-alpha-D-glucan = D-fructose + a (1->6)-alpha-D-glucan CA containing a (1->3)-alpha-D-glucose branch. CC -!- The enzyme from Leuconostoc spp. is responsible for producing alpha- CC (1->3) branches in alpha-(1->6) glucans by transferring the glucose CC residue from fructose to a 3-hydroxyl group of a glucan. //
