Title:
MDH GENE-BASED POLYNUCLEOTIDE HAVING PROMOTER ACTIVITY AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/257758
Kind Code:
A1
Abstract:
A polynucleotide having promoter activity of a malate dehydrogenase gene (mdh gene), a transcription expression cassette, recombinant expression vector and recombinant host cell containing the polynucleotide having the promoter activity, a method for constructing a promoter mutant, a method for regulating the transcription of a target gene, a method for preparing a protein, and method for producing a target compound. The polynucleotide having the promoter activity is a mutant of an mdh gene promoter, and compared with a promoter of a wild-type mdh gene, the promoter activity of the mutant is significantly improved. After operably linking the mutant to a target gene, the expression efficiency of the target gene can be significantly improved, thereby effectively improving the yield and transformation rate of a target compound.
