A reaction solution comprising a glucosyltransferase enzyme for synthesizing water, sucrose and poly-alpha-1,3-glucan is disclosed herein. The glucosyltransferase enzyme can synthesize an insoluble glucan polymer having an alpha-1,3 glycoside bond of 50% or more and a number average degree of polymerization of 100 or more. Furthermore, a method for producing insoluble poly-alpha-1,3-glucan by using such glucosyltransferase enzyme is disclosed. |
