Abstract
Yeast is genetically engineered by transformation with an expression vector containing a natural yeast secretion signal sequence combined appropriately with a chemically synthesized gene encoding antifreeze protein resulting in the expression, proper processing, and secretion of antifreeze protein which is heterologous to yeast in recoverable amounts. Disclosed are DNA sequences comprising structural genes encoding peptides having amino acid sequences with the biochemical or physiochemical properties of antifreeze protein and a method of combining the antifreeze protein gene sequences with appropriate expression vectors.
