Genetické modifikace v drahách biosyntéz aminokyselin s rozvětveným řetězcem u Corynebacterium glutamicum
Pátek, Miroslav ; Holátko, Jiří ; Elišáková, Veronika
Biosynthesis pathways of branched-chain amino acids (valine, leucine, isoleucine) are controlled by a complex regulatory system. To improve valine production by C. glutamicum, modifications (mutations) of promotersof genes ilvA, ilvB, ilvD, ilvE and leuA were constructed within the chromosome. The modulations of promoter strength (up or down mutations) resulted in an efficient valine producer
Modulace metabolických toků biosyntetickými drahami aminokyselin s větveným řetězcem u Corynebacterium glutamicum
Pátek, Miroslav ; Elišáková, Veronika ; Holátko, Jiří
Metabolic fluxes in pathways of biosynthesis of branched-chain amino acids can be modulated by different changes in expression of genes of the desired pathway as well as those of competing pathways. Site-directed mutagenesis of promoters of the respective genes is a suitable tool to obtain desired changes in gene expression.
Konstrukce kmenů Corynebacterium glutamicum s nadprodukcí valinu
Elišáková, Veronika ; Holátko, Jiří ; Pátek, Miroslav
Promoters of genes involved in biosynthesis of branched-chain amino acids in Corynebacterium glutamicum were mutagenized. The promoters with increased or decreased activities were used for construction of novel valine-overproducing strains
