More Information
Summary:Methods for producing poly alpha-1,3-glucan are disclosed herein. The methods comprise contacting at least water, sucrose, and a glucosyltransferase enzyme that comprises an amino acid sequence that is at least 99% identical to SEQ ID NO:4, whereby poly alpha-1,3-glucan is produced having at least 95% alpha-1,3 glycosidic linkages and a number average degree of polymerization of at least 100.
