ABSTRACT:
The invention provides a novel starch branching enzyme that is bound to A-type starch granules in wheat, barley, rye or triticale. The enzyme is not substantially associated with B-type starch granules. A cDNA sequence encoding an isoform of the enzyme has been isolated from the wheat cultivar Fielder and deduced amino acid sequence has been determined.
