METHODS FOR PRODUCING MAMMALIAN TRYPSINS

摘要

The present invention relates to methods for producing a mammalian trypsin in a Fusarium venenatum host strain, comprising (a) cultivating the Fusarium venenatum host strain in a culture medium under conditions suitable for expression of the mammalian trypsin and secretion thereof into the medium, wherein the Fusarium venenatum host strain comprises a nucleic acid construct comprising a nucleic acid sequence encoding the mature coding sequence of a mammalian trypsin operably linked to nucleotides 58 to 129 of SEQ ID NO: 1 encoding the signal peptide and propeptide of Fusarium oxysporum trypsinogen; and (b) recovering the mammalian trypsin from the medium. The present invention also relates to constructs comprising a nucleic acid sequence encoding the mature coding sequence of a mammalian trypsin operably linked to nucleotides 58 to 129 of SEQ ID NO: 1 encoding the signal peptide and propeptide of Fusarium oxysporum trypsinogen, and to vectors and Fusarium venenatum host strains comprising such constructs.
