Abstract
The present invention is directed to C-terminal truncated α-amylase polypeptides, nucleic acid sequences encoding the truncated α-amylase polypeptides, and methods of using the same. Further provided are expression cassettes, plants and plant parts expressing the nucleic acid sequence encoding the truncated α-amylase. Expression of the truncated α-amylase in a plant cell results in enhanced accumulation of biologically-active α-amylase, or enhanced secretion of the α-amylase from the plant cell, compared to the accumulation or secretion of a full length α-amylase.
