  • Publication number: 20110053218
    Abstract: A multiple promoter platform for expression of a protein or multiple and different proteins in a microorganism comprising two or more expression vectors having a nucleic acid molecule encoding a protein to be expressed, or having different nucleic acid molecules encoding different proteins to be expressed, wherein each vector has a different promoter operably linked to the nucleic acid molecule, and uses of the multiple promoter platform to produce recombinant proteins.

  • Patent number: 7771974
    Abstract: A method for gene shuffling to form a mutant or chimeric gene, the method comprising: (a) assigning one or more segments of one or more genes based on regions of encoded amino acid sequence; (b) amplifying the one or more assigned segments of the gene using primers specific for each segment; and (c) causing recombination of the one or more amplified segments to form a mutant or chimeric gene. An oligonucleotide primer suitable for use in gene shuffling, the primer having a non-degenerate core based on a segment or template of a gene to be amplified, and the core being flanked by both 5? and 3? degenerate ends.

  • Patent number: 6011147
    Abstract: A method is described for the identification and cloning of promoters that express under a defined environmental condition, such as growth in glucose medium. Using this method, five Trichodermal promoters capable of the high expression of operably linked coding sequences are identified, one of which is the promoter for T. reesei tef1. Also provided are altered cbh1 promoters, altered so that glucose no longer represses expression from such promoter. The invention further provides vectors and hosts that utilize such promoters, and unique fungal enzyme compositions from such hosts.

    Assignee: Rohm Enzyme Finland Oy
    Inventors: Tiina Hannele Nakari, Maija-Leena Onnela, Marja Hannele Ilmen, Kaisu Milja Helena Nevalainen, Merja Elisa Penttila
  • Patent number: 5837515
    Abstract: The structure of the T. reesei xln1 and xln2 genes and the primaru structure of proteins are described. Enzyme preparations enriched in hemicellulase enzymes are described. Such enzyme preparations may also be partially or completely deficient in cellulose degrading activity. Such preparations may be utilized in an crude, unpurified form and are especially useful in the production of pulp and paper.

  • Patent number: 5529919
    Abstract: Described are methods and means for the construction of strains of yeast capable of producing cellulolytic enzymes. This is achieved by the transfer of chromosomal genes or cDNA copies of mRNAs coding for cellulolytic enzymes isolated from the fungus Trichoderma reesei to yeast cells using recombinant DNA vectors capable of replicating in yeast. The correct expression of these cellulolytic genes in yeast leads to the production of cellulolytic enzymes which are secreted from the cell. This allows the yeast to hydrolyze 3-1,4-glucan substrates such as cellulose.
