    摘要: The present invention relates to recombinant-DNA-technology, and particularly to genes involved in the control of basic metabolic processes in fungi. The invention specifically provides a mutated form of the native glucose repressor gene cre of filamentous fungi, wherein the mutation is situated in the C-terminal domain, the N-terminal first zinc finger being intact and the C-terminal region including the second zinc finger being mutated so that the viability of a strain carrying said mutated gene is maintained and the glucose repression is relieved.

    摘要: The invention relates to a method and test kit for quantitative determination of the amounts or relative proportions of polynucleotides in a mixture. The invention enables assessment of dynamic variations in a mixed population of organisms using affinity aided solution hybridization. The test kit comprises organized pools of polynucleotide probes having approximately the same number of nucleotides, which are distinguishable using resolution enabling tags providing the probes with different sizes. The resolution enabling tags may simultaneously act as tracer, affinity or primer tags. The probes are allowed to hybridize with affinity tagged analyte polynucleotides. The result is hybrids, recoverable on separation aiding tools provided with counterparts of the affinity tag. After the quantitative release of the probes, the individual probes can be amplified and recorded. The method and test kit are useful for determining hygienic and epidemiologic situations and evaluating the effect of antibiotic treatment and sanitary measures.

    摘要: This invention relates to recombinant-DNA-technology. Specifically this invention relates to new recombinant yeast cells transformed with SEB1 gene. Yeast cells transformed with several copies of SEB1 gene, or overexpressing the Seb1 protein by some other means, have an increased capacity to produce secreted foreign or endogenous proteins. Further, said new recombinant cells, when transformed with genes expressing suitable hydrolytic enzymes can utilize appropriate macromolecular compounds more efficiently, which results in increased cell mass production and/or more versatile utilization of the compounds in relevant biotechnical applications.
