  • Patent number: 7888489
    Abstract: The invention relates to a nucleotide sequence comprising; a synonymous nucleotide coding sequence with optimized codon frequency such that a native codon has been exchanged with a synonymous codon, the synonymous codon encoding the same amino acid as the native codon and having a higher frequency in codon usage as defined in Table 1 than the native codon; and optionally the nucleotide sequence comprises control sequences such as; one translational termination sequence orientated in 5? towards 3? direction selected from the following list of sequences; TAAG, TAGA and TAAA, preferably TAAA, and/or one translational initiator coding sequence orientated in 5? towards 3? direction selected from the following list of sequences; gctnccyyc (SEQ ID NO:20), using ambiguity codes for nucleotides; v (A/C/G); n (A/C/G/T), preferably 5?-GCT TCC TTC-3? (SEQ ID NO:21).

  • Patent number: 6013489
    Abstract: The invention relates to isolation of an Aspergillus gene encoding rhamnogalacturonase (RG-ase) and the construction of recombinant Aspergillus strains with overexpression of RG-ase. These strains can be used for the commercial production of RG-ase. RG-ase is an important enzyme in processes requiring the degradation and/or modification of pectin or modification of pectin-containing vegetable or plant cell wall material. RG-ase may be used in various applications, including the processing of fruits and vegetables, in the extraction of components from vegetable material or for improving the functionality of pectin or pectin-containing vegetable material, food material or plant cell wall material.

  • Patent number: 5705358
    Abstract: Methods are described for the isolation and characterization of DNA sequences from Aspergillus niger var. awamori which are involved in the expression and secretion of endoxylanase II (exlA) by said Aspergillus mould. A process using these expression and/or secretion regulating regions to direct the production and optionally the secretion of proteins other than endoxylanase II by transformed moulds is provided.
