Abstract:
A cDNA clone from barley, pAGL. 2737, SEQ ID NO: 3, which encodes the enzyme. alpha. -glucosidase, is disclosed. A vector and microbial host containing a DNA sequence coding for the expression of barley. alpha. -glucosidase, and a DNA construct comprising a DNA sequence coding for the expression of barley. alpha. -glucosidase, together with a promoter located 5' to the DNA coding sequence and a 3' termination sequence, are also disclosed.
