Abstract
An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.

1-13. (canceled)
A method of producing an alpha-glucan, said method comprising:
- (a) combining at least sucrose and an isolated polypeptide comprising an amino acid sequence having at least 90% identity to SEQ ID NO:7, SEQ ID NO:9, or SEQ ID NO:13 under suitable aqueous reaction conditions to catalyze synthesis of water-soluble alpha-glucan comprising 100% alpha-1,6 glycosidic linkages.
