The present invention is related to a recombinant host cell, in particular a yeast cell, comprising a dihydroxy-acid dehydratase polypeptide. The invention is also related to a recombinant host cell having increased specific activity of the dihydroxy-acid dehydratase polypeptide as a result of increased expression of the polypeptide, modulation of the Fe—S cluster biosynthesis of the cell, or a combination thereof. The present invention also includes methods of using the host cells, as well as, methods for identifying polypeptides that increase the flux in an Fe—S cluster biosynthesis pathway in a host cell.
本发明涉及一种含有二羟基酸脱水酶多肽的重组宿主细胞,特别是酵母细胞。本发明还涉及一种重组宿主细胞,由于该多肽表达量的增加、细胞中Fe-S簇生物合成的调节或它们的组合,该细胞中二羟基酸脱水酶多肽的特异性活性增加。本发明还包括使用宿主细胞的方法,以及鉴定增加宿主细胞中Fe-S簇生物合成途径通量的多肽的方法。
