Protein expression

摘要

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.
