摘要:
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.
摘要:
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.

摘要:
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.
摘要:
Enzyme preparations enriched in hemicellulase-, pectin-, and/or lignin-degrading enzymes are described which are also partially or completely deficient in cellulase degrading activity. Such preparations may be utilized in an crude, unpurified form and are especially useful in the production of pulp and paper.
摘要:
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.
