FIELD: biotechnology.
SUBSTANCE: invention is a mutant of the promoter of the pyruvate carboxylase gene of Corynebacterium glutamicum. This mutant has improved promoter activity compared to the wild type promoter and can be used to increase the expression of the target gene.
EFFECT: functional ligation of the specified mutant with the pyruvate carboxylase gene increases the intensity of pyruvate carboxylase expression, thereby improving the efficiency of amino acid production by the strain.
