Abstract
DNA constructs that are useful for providing secretory expression of heterologous polypeptides in yeast comprising a DNA sequence that includes a Kluyveromyces .alpha.-factor leader sequence linked to the heterologous polypeptide by a yeast processing signal. Constructs employing the K. lactis .alpha.-factor leader and processing signal sequences, with and without spacer, linked to prochymosin are exemplified.
