    • The present invention relates to a genetically modified yeast cell comprising: —at least one recombinant promoter operably linked to at least one gene encoding a polypeptide or protein supporting the biosynthesis of polypeptides or proteins within said cell, said at least one gene being located at the native genomic locus of the genetically unmodified wild-type yeast cell, wherein the naturally occurring promoter of the at least one gene encoding the biosynthesis supporting polypeptide or protein is inactivated by at least one mutation within said naturally occurring promoter and, —a secretion cassette comprising a recombinant nucleic acid molecule encoding a protein or polypeptide of interest and a method for producing a recombinant protein or polypeptide of interest using such a cell.
    • 本发明涉及遗传修饰的酵母细胞,其包含:至少一个重组启动子,其可操作地连接至编码支持所述细胞内的多肽或蛋白质的生物合成的多肽或蛋白质的至少一个基因,所述至少一个基因位于 遗传性未修饰的野生型酵母细胞的天然基因组座位,其中编码所述生物合成支持多肽或蛋白质的所述至少一个基因的天然存在的启动子通过所述天然存在的启动子内的至少一个突变而失活,以及包含 编码感兴趣的蛋白质或多肽的重组核酸分子和使用这种细胞产生感兴趣的重组蛋白质或多肽的方法。
