    摘要: The present invention provides a method for the recombinant expression of polypeptides originating from gram negative bacteria, in a fungal host suitable for industrial production. In a first aspect the present invention relates to a method for recombinant expression of a polypeptide from a gram negative bacterium in a fungal host cell, comprising the steps: i) providing a nucleic acid sequence encoding the polypeptide, said nucleic acid sequence comprising a first nucleic acid sequence encoding a fungal signal peptide and a second nucleic acid sequence encoding the polypeptide, having at least one modified codon, wherein the modification does not change the amino acid encoded by said codon and the nucleic acid sequence of said codon is different compared to the corresponding codon in the wild type nucleic acid sequence present in the said gram negative bacterium; ii) expressing the modified nucleic acid sequence in the fungal host.

    摘要: The inventors have isolated novel lipolytic enzyme genes with a high homology to the T. lanuginosus lipase gene and thus well suited for use in gene shuffling. Accordingly, the invention provides a method of generating genetic diversity into lipolytic enzymes by family shuffling of two or more homologous genes which encode lipolytic enzymes. The DNA shuffling technique is used to create a library of shuffled genes, and this is expressed in a suitable expression system and the expressed proteins are screened for lipolytic enzyme activity. The invention also provides a polynucleotide comprising a nucleotide sequence encoding a lipolytic enzyme and a lipolytic enzyme (a polypeptide with lipolytic enzyme activity).
