摘要： The present invention is directed to recombinant microorganisms comprising one or more dihydroxyacid dehydratase (DHAD)-requiring biosynthetic pathways and methods of using said recombinant microorganisms to produce beneficial metabolites derived from said DHAD-requiring biosynthetic pathways. In various aspects of the invention, the recombinant microorganisms may be engineered to overexpress one or more polynucleotides encoding one or more Nfs1 proteins or homologs thereof and/or one or more polynucleotides encoding one or more Isd11 proteins or homologs thereof. In some embodiments, the recombinant microorganisms may comprise a cytosolically localized DHAD enzyme. In additional embodiments, the recombinant microorganisms may comprise a mitochondrially localized DHAD enzyme. In various embodiments described herein, the recombinant microorganisms may be microorganisms of the Saccharomyces clade, Crabtree-negative yeast microorganisms, Crabtree-positive yeast microorganisms, post-WGD (whole genome duplication) yeast microorganisms, pre-WGD (whole genome duplication) yeast microorganisms, and non-fermenting yeast microorganisms.

摘要： The present invention relates to a novel thermophile-derived keratinase having keratin decomposition ability. Further, the present invention relates to a polynucleotide encoding the keratinase, a recombinant vector containing the same, host cells transformed by using the recombinant vector, and a method for preparing a keratinase including a step of culturing the host cells. Further, the present invention relates to a composition for decomposing keratin containing the enzyme; and a method for decomposing keratin by using the same. Further, the present invention relates to a keratin decomposed product decomposed by the enzyme.The keratinase according to the present invention rapidly and effectively decomposes hardly-decomposable keratin, and thus it is expected that the keratinase can be used for the effective treatment and the high value-added resource recovery of agricultural and livestock waste, which causes environmental problems (for example, a novel material for enzyme cosmetics), and can be used in an innovative enzymatic bioconversion technique utilizing various decomposition enzyme groups.

摘要： The purpose of the present invention is to provide an organism having an ergothioneine productivity that is capable of easily producing ergothioneine within a short period of time at a high yield, as compared with a conventional technology, and, therefore, enables ergothioneine production on an industrial scale. This purpose can be achieved by a transformed fungus into which a gene encoding enzyme (1) or genes encoding enzymes (1) and (2) have been inserted and in which the inserted gene(s) are overexpressed. (1) an enzyme catalyzing a reaction of synthesizing hercynyl cysteine sulfoxide from histidine and cysteine in the presence of S-adenosyl methionine, iron (II) and oxygen. (2) An enzyme catalyzing a reaction of synthesizing ergothioneine from hercynyl cysteine sulfoxide using pyridoxal 5′-phosphate as a coenzyme.
