  • Leucine aminopeptidases produced recombinantly from Aspergillus soyae
    Patent number: 6228632
    Abstract: This invention relates to a recombinant deoxyribonucleic acid (DNA) which can be isolated from Aspergillus soyae, characterised in that it codes for a leucine aminopeptidase (LAP) and comprises a nucleotide sequence corresponding to the nucleotide sequence given in SEQ ID NO: 1 for the mature LAP or to a nucleotide sequence derived therefrom which hybridises under stringent conditions with the nucleotide sequence given in SEQ ID NO: 1 for the mature LAP. The invention further relates to vectors and transformed host organisms, and also relates to methods of producing LAP. Enzyme products for the production of protein hydrolysates, as well as protein hydrolysates which are produced correspondingly, also form part of the invention.
