Abstract
The present invention concerns a novel DNA sequence coding for an Aspergillus aspartic protease, an Aspergillus aspartic protease per se and a method for the preparation thereof. The invention further concerns a novel Aspergillus mutant strain defective in a protease of the aspartic proteinase-type, which is useful for the expression of heterologous protein, and a method for the preparation of such a mutant strain.
